-+# Contributor Covenant Code of Conduct
-+
-+## Our Pledge
-+
-+In the interest of fostering an open and welcoming environment, we as
-+contributors and maintainers pledge to making participation in our project and
-+our community a harassment-free experience for everyone, regardless of age, body
-+size, disability, ethnicity, gender identity and expression, level of experience,
-+nationality, personal appearance, race, religion, or sexual identity and
-+orientation.
-+
-+## Our Standards
-+
-+Examples of behavior that contributes to creating a positive environment
-+include:
-+
-+* Using welcoming and inclusive language
-+* Being respectful of differing viewpoints and experiences
-+* Gracefully accepting constructive criticism
-+* Focusing on what is best for the community
-+* Showing empathy towards other community members
-+
-+Examples of unacceptable behavior by participants include:
-+
-+* The use of sexualized language or imagery and unwelcome sexual attention or
-+advances
-+* Trolling, insulting/derogatory comments, and personal or political attacks
-+* Public or private harassment
-+* Publishing others' private information, such as a physical or electronic
-+ address, without explicit permission
-+* Other conduct which could reasonably be considered inappropriate in a
-+ professional setting
-+
-+## Our Responsibilities
-+
-+Project maintainers are responsible for clarifying the standards of acceptable
-+behavior and are expected to take appropriate and fair corrective action in
-+response to any instances of unacceptable behavior.
-+
-+Project maintainers have the right and responsibility to remove, edit, or
-+reject comments, commits, code, wiki edits, issues, and other contributions
-+that are not aligned to this Code of Conduct, or to ban temporarily or
-+permanently any contributor for other behaviors that they deem inappropriate,
-+threatening, offensive, or harmful.
-+
-+## Scope
-+
-+This Code of Conduct applies both within project spaces and in public spaces
-+when an individual is representing the project or its community. Examples of
-+representing a project or community include using an official project e-mail
-+address, posting via an official social media account, or acting as an appointed
-+representative at an online or offline event. Representation of a project may be
-+further defined and clarified by project maintainers.
-+
-+## Enforcement
-+
-+Instances of abusive, harassing, or otherwise unacceptable behavior may be
-+reported by contacting the project owner at greg@unrelenting.technology. All
-+complaints will be reviewed and investigated and will result in a response that
-+is deemed necessary and appropriate to the circumstances. The project owner is
-+obligated to maintain confidentiality with regard to the reporter of an incident.
-+Further details of specific enforcement policies may be posted separately.
-+
-+Project maintainers who do not follow or enforce the Code of Conduct in good
-+faith may face temporary or permanent repercussions as determined by other
-+members of the project's leadership.
-+
-+## Attribution
-+
-+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
-+available at [http://contributor-covenant.org/version/1/4][version]

-+# devd-rs
-+
-+A Rust library for listening to FreeBSD (also DragonFlyBSD) [devd](https://www.freebsd.org/cgi/man.cgi?devd)'s device attach-detach notifications.
-+
-+Listens on `/var/run/devd.seqpacket.pipe` and parses messages using [nom](https://github.com/Geal/nom).
-+
-+## Usage

-+# Change Log
-+
-+## [Unreleased][unreleased]
-+
-+### Changed
-+
-+## 1.2.4 - 2016-07-20
-+
-+### Thanks
-+- @Phlosioneer for documentation fixes
-+- @sourrust for fixing offsets in `take_bits!`
-+- @ChrisMacNaughton for the XFS crate
-+- @pwoolcoc for `rest_s`
-+- @fitzgen for more `IResult` methods
-+- @gtors for the negative lookahead feature
-+- @frk1 and @jeandudey for little endian float parsing
-+- @jethrogb for fixing input usage in `many1`
-+- @acatton for beating me at nom golf :D
-+
-+### Added
-+- the `rest_s` method on `IResult` returns the remaining `&str` input
-+- `unwrap_err` and `unwrap_inc` methods on `IResult`
-+- `not!` will peek at the input and return `Done` if the underlying parser returned `Error` or `Incomplete`, without consuming the input
-+- `le_f32` and `le_f64` parse little endian floating point numbers (IEEE 754)
-+-
-+
-+### Fixed
-+- documentation fixes
-+- `take_bits!` is now more precise
-+- `many1` inccorectly used the `len` function instead of `input_len`
-+- the INI parser is simpler
-+- `recognize!` had an early `return` taht is removed now
-+
-+## 1.2.3 - 2016-05-10
-+
-+### Thanks
-+- @lu-zero for the contribution guidelines
-+- @GuillaumeGomez for fixes on `length_bytes` and some documentation
-+- @Hywan for ducomentation and test fixes
-+- @Xirdus for correct trait import issues
-+- @mspiegel for the new AST example
-+- @cholcombe973 for adding the `cond_with_error!` combinator
-+- @tstorch for refactoring `many0!`
-+- @panicbit for the folding combinators
-+- @evestera for `separated_list!` fixes
-+- @DanielKeep for correcting some enum imports
-+
-+### Added
-+- Regular expression combinators starting with `re_bytes_` work on byte slices
-+- example parsing arithmetic expressions to an AST
-+- `cond_with_error!` works like `cond!` but will return `None` if the condition is false, and `Some(value)` if the underlying parser succeeded
-+- `fold_many0!`, `fold_many1!` and `fold_many_m_n!` will take a parser, an initial value and a combining function, and fold over the successful applications of the parser
-+
-+### Fixed
-+- `length_bytes!` converts the result of its child parser to usize
-+- `take_till!` now imports `InputLength` instead of assuming it's in scope
-+- `separated_list!` and `separated_nonempty_list!` will not consume the separator if there's no following successfully parsed value
-+- no more warnings on build
-+
-+### Changed
-+- simpler implementation of `many0!`
-+
-+## 1.2.2 - 2016-03-09
-+
-+### Thanks
-+- @conradev for fixing take_until_s!`
-+- @GuillaumeGomez for some documentation fixes
-+- @frewsxcv for some documentation fixes
-+- @tstorch for some test refactorings
-+
-+### Added
-+- `nom::Err` now implements `std::error::Error`
-+
-+### Fixed
-+- `hex_u32` does not parses more than 8 chars now
-+- `take_while!` and `take_while1!` will not perturb the behaviour of `recognize!` anymore
-+
-+## 1.2.1 - 2016-02-23
-+
-+### Thanks
-+- @sourrust for adding methods to `IResult`
-+- @tstorch for the test refactoring, and for adding methods to `IResult` and `Needed`
-+- @joelself for fixing the method system
-+
-+### Added
-+
-+- mapping methods over `IResult` and `Needed`
-+
-+### Changed
-+
-+- `apply_rf` is renamed to `apply_m`. This will not warrant a major version, since it is part missing from the methods feture added in the 1.2.0 release
-+- the `regexp_macros` feature that used `regex!` to precompile regular expressions has been replaced by the normal regex engine combined with `lazy_static`
-+
-+### Fixed
-+
-+- when a parser or combinator was returning an empty buffer as remaining part, it was generating one from a static empty string. This was messing with buffer offset calculation. Now, that empty slice is taken like this: `&input[input.len()..]`.
-+- The `regexp_macros` and `no_std` feature build again and are now tested with Travis CI
-+
-+## 1.2.0 - 2016-02-08
-+
-+### Thanks
-+- @zentner-kyle for type inference fixes
-+- @joelself for his work on `&str` parsing and method parsers
-+- @GuillaumeGomez for implementing methods on `IResult`
-+- @dirk for the `alt_complete!` combinator
-+- @tstorch for a lot of refactoring work and unit tests additions
-+- @jansegre for the hex digit parsers
-+- @belgum for some documentation fixes
-+- @lwandrebeck for some documentation fixes and code fixes in `hex_digit`
-+
-+### Added
-+- `take_until_and_consume_s!` for consumption of string data until a tag
-+- more function patterns in `named!`. The error type can now be specified
-+- `alt_complete!` works like the `alt!` combinator, but tries the next branch if the current one returned `Incomplete`, instead of returning directly
-+- more unit tests for a lot of combinators
-+- hexadecimal digit parsers
-+- the `tuple!` combinator takes a list of parsers as argument, and applies them serially on the input. If all of them are successful, it willr eturn a tuple accumulating all the values. This combinator will (hopefully) replace most uses of `chain!`
-+- parsers can now be implemented as a method for a struct thanks to the `method!`, `call_m!` and `apply_rf!` combinators
-+
-+### Fixed
-+- there were type inference issues in a few combinators. They will now be easier to compile
-+- `peek!` compilation with bare functions
-+- `&str` parsers were splitting data at the byte level, not at the char level, which can result in inconsistencies in parsing UTF-8 characters. They now use character indexes
-+- some method implementations were missing on `ÌResult<I,O,E>` (with specified error type instead of implicit)
-+
-+## 1.1.0 - 2016-01-01
-+
-+This release adds a lot of features related to `&str` parsing. The previous versions
-+were focused on `&[u8]` and bit streams parsing, but there's a need for more text
-+parsing with nom. The parsing functions like `alpha`, `digit` and others will now
-+accept either a `&[u8]` or a `&str`, so there is no breaking change on that part.
-+
-+There are also a few performance improvements and documentation fixes.
-+
-+### Thanks
-+- @Binero for pushing the work on `&str` parsing
-+- @meh for fixing `Option` and `Vec` imports
-+- @hoodie for a documentation fix
-+- @joelself for some documentation fixes
-+- @vberger for his traits magic making `nom functions more generic
-+
-+### Added
-+
-+- string related parsers: `tag_s!`, `take_s!`, `is_a_s!`, `is_not_s!`, `take_while_s!`, `take_while1_s!`, `take_till_s!
-+- `value!` is a combinator that always returns the same value. If a child parser is passed as second argument, that value is returned when the child parser succeeds
-+
-+### Changed
-+
-+- `tag!` will now compare even on partial input. If it expects "abcd" but receives "ef", it will now return an `Error` instead of `Incomplete`
-+- `many0!` and others will preallocate a larger vector to avoid some copies and reallocations
-+- `alpha`, `digit`, `alphanumeric`, `space` and `multispace` now accept as input a `&[u8]` or a `&str`. Additionally, they return an error if they receive an empty input
-+- `take_while!`, `take_while1!`, `take_while_s!`, `take_while1_s!` wilreturn an error on empty input
-+
-+### Fixed
-+
-+- if the child parser of `many0!` or `many1!` returns `Incomplete`, it will return `Incomplete` too, possibly updating the needed size
-+- `Option,` `Some`, `None` and `Vec` are now used with full path imports
-+
-+## 1.0.1 - 2015-11-22
-+
-+This releases makes the 1.0 version compatible with Rust 1.2 and 1.3
-+
-+### Thanks
-+- @steveklabnik for fixing lifetime issues in Producers and Consumers
-+
-+## 1.0.0 - 2015-11-16
-+
-+Stable release for nom. A lot of new features, a few breaking changes
-+
-+### Thanks
-+- @ahenry for macro fixes
-+- @bluss for fixing documentation
-+- @sourrust for cleaning code and debugging the new streaming utilities
-+- @meh for inline optimizations
-+- @ccmtaylor for fixing function imports
-+- @soro for improvements to the streaming utilities
-+- @breard-r for catching my typos
-+- @nelsonjchen for catching my typos too
-+- @divarvel for hex string parsers
-+- @mrordinaire for the `length_bytes!` combinator
-+
-+### Breaking changes
-+- `IResult::Error` can now use custom error types, and is generic over the input type
-+- Producers and consumers have been replaced. The new implementation uses less memory and integrates more with parsers
-+- `nom::ErrorCode` is now `nom::ErrorKind`
-+- `filter!` has been renamed to `take_while!`
-+- `chain!` will count how much data is consumed and use that number to calculate how much data is needed if a parser returned `Incomplete`
-+- `alt!` returns `Incomplete` if a child parser returned `Incomplete`, instead of skipping to the next parser
-+- `IResult` does not require a lifetime tag anymore, yay!
-+
-+### Added
-+
-+- `complete!` will return an error if the child parser returned `Incomplete`
-+- `add_error!` will wrap an error, but allow backtracking
-+- `hex_u32` parser
-+
-+### Fixed
-+- the behaviour around `Incomplete` is better for most parsers now
-+
-+## 0.5.0 - 2015-10-16
-+
-+This release fixes a few issues and stabilizes the code.
-+
-+### Thanks
-+- @nox for documentation fixes
-+- @daboross for linting fixes
-+- @ahenry for fixing `tap!` and extending `dbg!` and `dbg_dmp!`
-+- @bluss for tracking down and fixing issues with unsafe code
-+- @meh for inlining parser functions
-+- @ccmtaylor for fixing import of `str::from_utf8`
-+
-+### Fixed
-+- `tap!`, `dbg!` and `dbg_dmp!` now accept function parameters
-+
-+### Changed
-+- the type used in `count_fixed!` must be `Copy`
-+- `chain!` calculates how much data is needed if one of the parsers returns `Incomplete
-+- optional parsers in `chain!` can return `Incomplete`
-+
-+## 0.4.0 - 2015-09-08
-+
-+Considering the number of changes since the last release, this version can contain breaking changes, so the version number becomes 0.4.0. A lot of new features and performance improvements!
-+
-+### Thanks
-+- @frewsxcv for documentation fixes
-+- @ngrewe for his work on producers and consumers
-+- @meh for fixes on `chain!` and for the `rest` parser
-+- @daboross for refactoring `many0!` and `many1!`
-+- @aleksander for the `switch!` combinator idea
-+- @TechnoMancer for his help with bit level parsing
-+- @sxeraverx for pointing out a bug in `is_a!`
-+
-+### Fixed
-+- `count_fixed!` must take an explicit type as argument to generate the fixed-size array
-+- optional parsing behaviour in `chain!`
-+- `count!` can take 0 elements
-+- `is_a!` and `is_not!` can now consume the whole input
-+
-+### Added
-+- it is now possible to seek to the end of a `MemProducer`
-+- `opt!` returns `Done(input, None)` if `the child parser returned `Incomplete`
-+- `rest` will return the remaining input
-+- consumers can now seek to and from the end of input
-+- `switch!` applies a first parser then matches on its result to choose the next parser
-+- bit-level parsers
-+- character-level parsers
-+- regular expression parsers
-+- implementation of `take_till!`, `take_while!` and `take_while1!`
-+
-+### Changed
-+- `alt!` can return `Incomplete`
-+- the error analysis functions will now take references to functions instead of moving them
-+- performance improvements on producers
-+- performance improvement for `filter!`
-+- performance improvement for `count!`: a `Vec` of the right size is directly allocated
-+
-+## 0.3.11 - 2015-08-04
-+
-+### Thanks
-+- @bluss for remarking that the crate included random junk lying non commited in my local repository
-+
-+### Fixed
-+- cleanup of my local repository will ship less files in the crates, resulting in a smaller download
-+
-+## 0.3.10 - 2015-08-03
-+
-+### Added
-+
-+- `bits!` for bit level parsing. It indicates that all child parsers will take a `(&[u8], usize)`as input, with the second parameter indicating the bit offset in the first byte. This allows viewing a byte slice as a bit stream. Most combinators can be used directly under `bits!`
-+- `take_bits!` takes an integer type and a number of bits, consumes that number of bits and updates the offset, possibly by crossing byte boundaries
-+- bit level parsers are all written in `src/bits.rs`
-+
-+### Changed
-+
-+- Parsers that specifically handle bytes have been moved to src/bytes.rs`. This applies to `tag!`, `is_not!`, `is_a!`, `filter!`, `take!`, `take_str!`, `take_until_and_consume!`, `take_until!`, `take_until_either_and_consume!`, `take_until_either!`
-+
-+## 0.3.9 - 2015-07-20
-+
-+### Thanks
-+- @badboy for fixing `filter!`
-+- @idmit for some documentation fixes
-+
-+### Added
-+- `opt_res!` applies a parser and transform its result in a Result. This parser never fails
-+- `cond_reduce!` takes an expression as parameter, applies the parser if the expression is true, and returns an error if the expression is false
-+- `tap!` pass the result of a parser to a block to manipulate it, but do not affect the parser's result
-+- `AccReader` is a Read+BufRead that supports data accumulation and partial consumption. The `consume` method must be called afterwardsto indicate how much was consumed
-+- Arithmetic expression evaluation and parsing example
-+- `u16!`, `u32!`, `u64!`, `i16!`, `i32!`, `i64!` take an expression as parameter, if the expression is true, apply the big endian integer parser, if false, the little endian version
-+- type information for combinators. This will make the documentation a bit easier to navigate
-+
-+### Fixed
-+- `map_opt!` and `map_res!` had issues with argument order due to bad macros
-+- `delimited!` did not compile for certain combinations of arguments
-+- `filter!` did not return a byte slice but a fixed array
-+
-+## 0.3.8 - 2015-07-03
-+
-+### Added
-+- code coverage is now calculated automatically on Travis CI
-+- `Stepper`: wrap a `Producer`, and call the method `step` with a parser. This method will buffer data if there is not enough, apply the parser if there is, and keep the rest of the input in memory for the next call
-+- `ReadProducer`: takes something implementing `Read`, and makes a `Producer` out of it
-+
-+### Fixed
-+- the combinators `separated_pair!` and `delimited!` did not work because an implementation macro was not exported
-+- if a `MemProducer` reached its end, it should always return `Eof`
-+- `map!` had issues with argument matching
-+
-+## 0.3.7 - 2015-06-24
-+
-+### Added
-+- `expr_res!` and `expr_opt!` evaluate an expression returning a Result or Opt and convert it to IResult
-+- `AsBytes` is implemented for fixed size arrays. This allows `tag!([41u8, 42u8])`
-+
-+### Fixed
-+- `count_fixed!` argument parsing works again
-+
-+## 0.3.6 - 2015-06-15
-+
-+### Added
-+- documentation for a few functions
-+- the consumer trait now requires the `failed(&self, error_code)` method in case of parsing error
-+- `named!` now handles thge alternative `named!(pub fun_name<OutputType>, ...)`
-+
-+### Fixed
-+- `filter!` now returns the whole input if the filter function never returned false
-+- `take!` casts its argument as usize, so it can accepts any integer type now
-+
-+## 0.3.5 - 2015-06-10
-+
-+### Thanks
-+- @cmr for some documentation fixes
-+
-+### Added
-+- `count_fixed!` returns a fixed array
-+
-+### Fixed
-+- `count!` is back to the previous behaviour, returning a `Vec` for sizes known at runtime
-+
-+### Changed
-+- functions and traits exported from `nom::util` are now directly in `nom::`
-+
-+## 0.3.4 - 2015-06-09
-+
-+### Thanks
-+- @andrew-d for fixes on `cond!`
-+- @keruspe for features in `chain!`
-+
-+### Added
-+- `chain!` can now have mutable fields
-+
-+### Fixed
-+- `cond!` had an infinite macro recursion
-+
-+### Changed
-+- `chain!` generates less code now. No apprent compilation time improvement
-+
-+## 0.3.3 - 2015-06-09
-+
-+### Thanks
-+- @andrew-d for the little endian signed integer parsers
-+- @keruspe for fixes on `count!`
-+
-+### Added
-+- `le_i8`, `le_i16`, `le_i32`, `le_i64`: little endian signed integer parsers
-+
-+### Changed
-+- the `alt!` parser compiles much faster, even with more than 8 branches
-+- `count!` can now return a fixed size array instead of a growable vector
-+
-+## 0.3.2 - 2015-05-31
-+
-+### Thanks
-+- @keruspe for the `take_str` parser and the function application combinator
-+
-+### Added
-+- `take_str!`: takes the specified number of bytes and return a UTF-8 string
-+- `apply!`: do partial application on the parameters of a function
-+
-+### Changed
-+- `Needed::Size` now contains a `usize` instead of a `u32`
-+
-+## 0.3.1 - 2015-05-21
-+
-+### Thanks
-+- @divarvel for the big endian signed integer parsers
-+
-+### Added
-+- `be_i8`, `be_i16`, `be_i32`, `be_i64`: big endian signed integer parsers
-+- the `core` feature can be passed to cargo to build with `no_std`
-+- colored hexdump can be generated from error chains
-+
-+## 0.3.0 - 2015-05-07
-+
-+### Thanks
-+- @filipegoncalves for some documentation and the new eof parser
-+- @CrimsonVoid for putting fully qualified types in the macros
-+- @lu_zero for some documentation fixes
-+
-+### Added
-+- new error types that can contain an error code, an input slice, and a list of following errors
-+- `error!` will cut backtracking and return directly from the parser, with a specified error code
-+- `eof` parser, successful if there is no more input
-+- specific error codes for the parsers provided by nom
-+
-+### Changed
-+- fully qualified types in macros. A lot of imports are not needed anymore
-+
-+### Removed
-+- `FlatMap`, `FlatpMapOpt` and `Functor` traits (replaced by `map!`, `map_opt!` and `map_res!`)
-+
-+## 0.2.2 - 2015-04-12
-+
-+### Thanks
-+- @filipegoncalves and @thehydroimpulse for debugging an infinite loop in many0 and many1
-+- @thehydroimpulse for suggesting public named parsers
-+- @skade for removing the dependency on the collections gate
-+
-+### Added
-+- `named!` can now declare public functions like this: `named!(pub tst, tag!("abcd"));`
-+- `pair!(X,Y)` returns a tuple `(x, y)`
-+- `separated_pair!(X, sep, Y)` returns a tuple `(x, y)`
-+- `preceded!(opening, X)` returns `x`
-+- `terminated!(X, closing)` returns `x`
-+- `delimited(opening, X, closing)` returns `x`
-+- `separated_list(sep, X)` returns a `Vec<X>`
-+- `separated_nonempty_list(sep, X)` returns a `Vec<X>` of at list one element
-+
-+### Changed
-+- `many0!` and `many1!` forbid parsers that do not consume input
-+- `is_a!`, `is_not!`, `alpha`, `digit`, `space`, `multispace` will now return an error if they do not consume at least one byte
-+
-+## 0.2.1 - 2015-04-04
-+
-+### Thanks
-+- @mtsr for catching the remaining debug println!
-+- @jag426 who killed a lot of warnings
-+- @skade for removing the dependency on the core feature gate
-+
-+
-+### Added
-+- little endian unsigned int parsers le_u8, le_u16, le_u32, le_u64
-+- `count!` to apply a parser a specified number of times
-+- `cond!` applies a parser if the condition is met
-+- more parser development tools in `util::*`
-+
-+### Fixed
-+- in one case, `opt!` would not compile
-+
-+### Removed
-+- most of the feature gates are now removed. The only one still needed is `collections`
-+
-+## 0.2.0 - 2015-03-24
-+*works with `rustc 1.0.0-dev (81e2396c7 2015-03-19) (built 2015-03-19)`*
-+
-+### Thanks
-+- Ryman for the AsBytes implementation
-+- jag426 and jaredly for documentation fixes
-+- eternaleye on #rust IRC for his help on the new macro syntax
-+
-+### Changed
-+- the AsBytes trait improves readability, no more b"...", but "..." instead
-+- Incomplete will now hold either Needed;;Unknown, or Needed::Size(u32). Matching on Incomplete without caring for the value is done with `Incomplete(_)`, but if more granularity is mandatory, `Needed` can be matched too
-+- `alt!` can pass the result of the parser to a closure
-+- the `take_*` macros changed behaviour, the default case is now not to consume the separator. The macros have been renamed as follows: `take_until!` -> `take_until_and_consume!`, `take_until_and_leave!` -> `take_until!`, `take_until_either_and_leave!` -> `take_until_either!`, `take_until_either!` -> `take_until_either_and_consume!`
-+
-+### Added
-+- `peek!` macro: matches the future input but does not consume it
-+- `length_value!` macro: the first argument is a parser returning a `n` that can cast to usize, then applies the second parser `n` times. The macro has a variant with a third argument indicating the expected input size for the second parser
-+- benchmarks are available at https://github.com/Geal/nom_benchmarks
-+- more documentation
-+- **Unnamed parser syntax**: warning, this is a breaking change. With this new syntax, the macro combinators do not generate functions anymore, they create blocks. That way, they can be nested, for better readability. The `named!` macro is provided to create functions from parsers. Please be aware that nesting parsers comes with a small cost of compilation time, negligible in most cases, but can quickly get to the minutes scale if not careful. If this happens, separate your parsers in multiple subfunctions.
-+- `named!`, `closure!` and `call!` macros used to support the unnamed syntax
-+- `map!`, `map_opt!` and `map_res!` to combine a parser with a normal function, transforming the input directly, or returning an `Option` or `Result`
-+
-+### Fixed
-+- `is_a!` is now working properly
-+
-+### Removed
-+- the `o!` macro does less than `chain!`, so it has been removed
-+- the `fold0!` and `fold1!` macros were too complex and awkward to use, the `many*` combinators will be useful for most uses for now
-+
-+## 0.1.6 - 2015-02-24
-+### Changed
-+- consumers must have an end method that will be called after parsing
-+
-+### Added
-+- big endian unsigned int and float parsers: be_u8, be_u16, be_u32, be_u64, be_f32, be_f64
-+- producers can seek
-+- function and macros documentation
-+- README documentation
-+### Fixed
-+- lifetime declarations
-+- tag! can return Incomplete
-+
-+## 0.1.5 - 2015-02-17
-+### Changed
-+- traits were renamed: FlatMapper -> FlatMap, Mapper -> FlatMapOpt, Mapper2 -> Functor
-+
-+### Fixed
-+- woeks with rustc f1bb6c2f4
-+
-+## 0.1.4 - 2015-02-17
-+### Changed
-+- the chaining macro can take optional arguments with '?'
-+
-+## 0.1.3 - 2015-02-16
-+### Changed
-+- the chaining macro now takes the closure at the end of the argument list
-+
-+## 0.1.2 - 2015-02-16
-+### Added
-+- flat_map implementation for <&[u8], &[u8]>
-+- chaining macro
-+- partial MP4 parser example
-+
-+
-+## 0.1.1 - 2015-02-06
-+### Fixed
-+- closure syntax change

-+//! Bit level parsers and combinators
-+//!
-+//! Bit parsing is handled by tweaking the input in most macros.
-+//! In byte level parsing, the input is generally a `&[u8]` passed from combinator
-+//! to combinator until the slices are manipulated.
-+//!
-+//! Bit parsers take a `(&[u8], usize)` as input. The first part of the tuple is an byte slice,
-+//! the second part is a bit offset in the first byte of the slice.
-+//!
-+//! By passing a pair like this, we can leverage most of the combinators, and avoid
-+//! transforming the whole slice to a vector of booleans. This should make it easy
-+//! to see a byte slice as a bit stream, and parse code points of arbitrary bit length.
-+
-+
-+/// `bits!( parser ) => ( &[u8], (&[u8], usize) -> IResult<(&[u8], usize), T> ) -> IResult<&[u8], T>`

-+//! nom, eating data byte by byte
-+//!
-+//! nom is a parser combinator library with a focus on safe parsing,
-+//! streaming patterns, and as much as possible zero copy.
-+//!
-+//! The code is available on [Github](https://github.com/Geal/nom)
-+//!
-+//! # Example
-+//!
-+//! ```
-+//! #[macro_use]
-+//! extern crate nom;
-+//!
-+//! use nom::{IResult,digit};
-+//! use nom::IResult::*;
-+//!

-+//! // We transform an integer string into a i64
-+//! // we look for a digit suite, and try to convert it.

-+//! // the parser will fail

-+//! Macro combinators
-+//!
-+//! Macros are used to make combination easier,
-+//! since they often do not depend on the type
-+//! of the data they manipulate or return.
-+//!
-+//! There is a trick to make them easier to assemble,
-+//! combinators are defined like this:
-+//!
-+//! ```ignore
-+//! macro_rules! tag (
-+//! ($i:expr, $inp: expr) => (
-+//! {
-+//! ...
-+//! }
-+//! );
-+//! );
-+//! ```
-+//!
-+//! But when used in other combinators, are Used
-+//! like this:
-+//!
-+//! ```ignore
-+//! named!(my_function, tag!("abcd"));
-+//! ```
-+//!
-+//! Internally, other combinators will rewrite
-+//! that call to pass the input as first argument:
-+//!
-+//! ```ignore
-+//! macro_rules! named (
-+//! ($name:ident, $submac:ident!( $($args:tt)* )) => (
-+//! fn $name<'a>( i: &'a [u8] ) -> $crate::IResult<'a,&[u8], &[u8]> {
-+//! $submac!(i, $($args)*)
-+//! }
-+//! );
-+//! );
-+//! ```
-+//!
-+//! If you want to call a combinator directly, you can
-+//! do it like this:
-+//!
-+//! ```ignore
-+//! let res = { tag!(input, "abcd"); }
-+//! ```
-+//!
-+//! Combinators must have a specific variant for
-+//! non-macro arguments. Example: passing a function
-+//! to take_while! instead of another combinator.
-+//!
-+//! ```ignore
-+//! macro_rules! take_while(
-+//! ($input:expr, $submac:ident!( $($args:tt)* )) => (
-+//! {
-+//! ...
-+//! }
-+//! );
-+//!
-+//! // wrap the function in a macro to pass it to the main implementation
-+//! ($input:expr, $f:expr) => (
-+//! take_while!($input, call!($f));
-+//! );
-+//! );

-+///
-+/// **BE CAREFUL** there is a case where the behaviour of `alt!` can be confusing:
-+///
-+/// when the alternatives have different lengths, like this case:
-+///
-+/// ```ignore
-+/// named!( test, alt!( tag!( "abcd" ) | tag!( "ef" ) | tag!( "ghi" ) | tag!( "kl" ) ) );
-+/// ```
-+///
-+/// With this parser, if you pass `"abcd"` as input, the first alternative parses it correctly,
-+/// but if you pass `"efg"`, the first alternative will return `Incomplete`, since it needs an input
-+/// of 4 bytes. This behaviour of `alt!` is expected: if you get a partial input that isn't matched
-+/// by the first alternative, but would match if the input was complete, you want `alt!` to indicate
-+/// that it cannot decide with limited information.
-+///
-+/// There are two ways to fix this behaviour. The first one consists in ordering the alternatives
-+/// by size, like this:
-+///
-+/// ```ignore
-+/// named!( test, alt!( tag!( "ef" ) | tag!( "kl") | tag!( "ghi" ) | tag!( "abcd" ) ) );
-+/// ```
-+///
-+/// With this solution, the largest alternative will be tested last.
-+///
-+/// The other solution uses the `complete!` combinator, which transforms an `Incomplete` in an
-+/// `Error`. If one of the alternatives returns `Incomplete` but is wrapped by `complete!`,
-+/// `alt!` will try the next alternative. This is useful when you know that
-+/// you will not get partial input:
-+///
-+/// ```ignore
-+/// named!( test,
-+/// alt!(
-+/// complete!( tag!( "abcd" ) ) |
-+/// complete!( tag!( "ef" ) ) |
-+/// complete!( tag!( "ghi" ) ) |
-+/// complete!( tag!( "kl" ) )
-+/// )
-+/// );
-+/// ```
-+///
-+/// If you want the `complete!` combinator to be applied to all rules then use the convenience
-+/// `alt_complete!` macro (see below).
-+///
-+/// This behaviour of `alt!` can get especially confusing if multiple alternatives have different
-+/// sizes but a common prefix, like this:
-+///
-+/// ```ignore
-+/// named!( test, alt!( tag!( "abcd" ) | tag!( "ab" ) | tag!( "ef" ) ) );
-+/// ```
-+///
-+/// in that case, if you order by size, passing `"abcd"` as input will always be matched by the
-+/// smallest parser, so the solution using `complete!` is better suited.
-+///
-+/// You can also nest multiple `alt!`, like this:
-+///
-+/// ```ignore
-+/// named!( test,
-+/// alt!(
-+/// preceded!(
-+/// tag!("ab"),
-+/// alt!(
-+/// tag!( "cd" ) |
-+/// eof
-+/// )
-+/// )
-+/// | tag!( "ef" )
-+/// )
-+/// );
-+/// ```
-+///
-+/// `preceded!` will first parse `"ab"` then, if successful, try the alternatives "cd",
-+/// or empty input (End Of File). If none of them work, `preceded!` will fail and
-+/// "ef" will be tested.

-+//! Method macro combinators
-+//!
-+//! These macros make parsers as methods of structs
-+//! and that can take methods of structs to call
-+//! as parsers.
-+//!
-+//! There is a trick to make them easier to assemble,
-+//! combinators are defined like this:
-+//!
-+//! ```ignore
-+//! macro_rules! tag (
-+//! ($i:expr, $inp: expr) => (
-+//! {
-+//! ...
-+//! }
-+//! );
-+//! );
-+//! ```
-+//!
-+//! But when used as methods in other combinators, are used
-+//! like this:
-+//!
-+//! ```ignore
-+//! method!(my_function<Parser<'a> >, self, tag!("abcd"));
-+//! ```
-+//!
-+//! Internally, other combinators will rewrite
-+//! that call to pass the input as second argument:
-+//!
-+//! ```ignore
-+//! macro_rules! method (
-+//! ($name:ident<$a:ty>, $self_:ident, $submac:ident!( $($args:tt)* )) => (
-+//! fn $name( $self_: $a, i: &[u8] ) -> $crate::IResult<&[u8], &[u8]> {
-+//! $submac!(i, $($args)*)
-+//! }
-+//! );
-+//! );
-+//! ```
-+//!
-+//! The `method!` macro is similar to the `named!` macro in the macros module.
-+//! While `named!` will create a parser function, `method!` will create a parser
-+//! method on the struct it is defined in.
-+//!
-+//! Compared to the `named!` macro there are a few differences in how they are
-+//! invoked. A `method!` invocation always has to have the type of `self`
-+//! declared and it can't be a reference due to Rust's borrow lifetime
-+//! restrictions:
-+//! ```ignore
-+//! // -`self`'s type-
-+//! method!(method_name< Parser<'a> >, ...);
-+//! ```
-+//! `self`'s type always comes first.
-+//! The next difference is you have to input the self struct. Due to Rust's
-+//! macro hygiene the macro can't declare it on it's own.
-+//! ```ignore
-+//! // -self-
-+//! method!(method_name<Parser<'a>, &'a str, &'a str>, self, ...);
-+//! ```
-+//! When making a parsing struct with parsing methods, due to the static borrow
-+//! checker,calling any parsing methods on self (or any other parsing struct)
-+//! will cause self to be moved for the rest of the method.To get around this
-+//! restriction all self is moved into the called method and then the called
-+//! method will return self to the caller.
-+//!
-+//! To call a method on self you need to use the `call_m!` macro. For example:
-+//! ```ignore
-+//! struct<'a> Parser<'a> {
-+//! parsed: &'a str,
-+//! }
-+//! impl<'a> Parser<'a> {
-+//! // Constructor omitted for brevity
-+//! method!(take4<Parser<'a>, &'a str, &'a str>, self, take!(4));
-+//! method!(caller<Parser<'a>, &'a str, &'a str>, self, call_m!(self.take4));
-+//! }
-+//! ```
-+//! More complicated combinations still mostly look the same as their `named!`
-+//! counterparts:
-+//! ```ignore
-+//! method!(pub simple_chain<&mut Parser<'a>, &'a str, &'a str>, self,
-+//! chain!(
-+//! call_m!(self.tag_abc) ~
-+//! call_m!(self.tag_def) ~
-+//! call_m!(self.tag_ghi) ~
-+//! last: call_m!(self.simple_peek) ,
-+//! ||{sb.parsed = last; last}
-+//! )
-+//! );
-+//! ```
-+//! The three additions to method definitions to remember are:
-+//! 1. Specify `self`'s type
-+//! 2. Pass `self` to the macro
-+//! 4. Call parser methods using the `call_m!` macro.
-+
-+/// Makes a method from a parser combination
-+///
-+/// The must be set up because the compiler needs
-+/// the information
-+///
-+/// ```ignore
-+/// method!(my_function<Parser<'a> >( &[u8] ) -> &[u8], tag!("abcd"));
-+/// // first type parameter is `self`'s type, second is input, third is output
-+/// method!(my_function<Parser<'a>, &[u8], &[u8]>, tag!("abcd"));
-+/// //prefix them with 'pub' to make the methods public
-+/// method!(pub my_function<Parser<'a>,&[u8], &[u8]>, tag!("abcd"));
-+/// ```

- ### Changed
-
-+## 3.2.1 - 2017-10-27
-+
-+### Thanks
-+
-+- @ordian for `alt_complete` fixes
-+- @friedm for documentation fixes
-+- @kali for improving error management
-+
-+### Fixed
-+
-+- there were cases where `alt_complete` could return `Incomplete`
-+
-+### Added
-+
-+- an `into_error_kind` method can be used to transform any error to a common value. This helps when the library is included multiple times as dependency with different feature sets
-+
-+
-+## 3.2.0 - 2017-07-24
-+
-+### Thanks
-+
-+- @jedireza for documentation fixes
-+- @gmorenz for the `bytes` combinator
-+- @meh for character combinator fixes for UTF-8
-+- @jethrogb for avoiding move issues in `separated_list`
-+
-+### Changed
-+
-+- new layout for the main page of documentation
-+- `anychar` can now work on any input type
-+- `length_bytes` is now an alias for `length_data`
-+
-+### Fixed
-+
-+- `one_of`, `none_of` and `char` will now index correctly UTF-8 characters
-+- the `compiler_error` macro is now correctly exported
-+
-+
-+### Added
-+
-+- the `bytes` combinator transforms a bit stream back to a byte slice for child parsers
-+
-+## 3.1.0 - 2017-06-16
-+
-+### Thanks
-+
-+- @sdroege: implementing be_i24 and le_i24
-+- @Hywan: integrating faster substring search using memchr
-+- @nizox: fixing type issues in bit stream parsing
-+- @grissiom: documentation fixes
-+- @doomrobo: implementing separated_list_complete and separated_nonempty_list_complete
-+- @CWood1: fixing memchr integration in no_std
-+- @lu_zero: integrating the compiler_error crate
-+- @dtolnay: helping debug a type inference issue in map
-+
-+### Changed
-+
-+- memchr is used for substring search if possible
-+- if building on nightly, some common syntax errors will display a specific error message. If building no stable, display the documentation to activate those messages
-+- `count` no longer preallocates its vector
-+
-+### Fixed
-+
-+- better type inference in alt_complete
-+- `alt` should now work with whitespace parsing
-+- `map` should not make type inference errors anymore
-+
-+### Added
-+
-+- be_i24 and le_i24, parsing big endian and little endian signed 24 bit integers
-+- `separated_list_complete` and `separated_nonempty_list_complete` will treat incomplete from sub parsers as error
-+
-+## 3.0.0 - 2017-05-12
-+
-+### Thanks
-+
-+- Chris Pick for some `Incomplete` related refactors
-+- @drbgn for documentation fixes
-+- @valarauca for adding `be_u24`
-+- @ithinuel for usability fixes
-+- @evuez for README readability fixes and improvements to `IResult`
-+- @s3bk for allowing non-`Copy` types as input

-+- @iBelieve for adding str to no_std
-+- @Hywan for simplifying code in input traits
-+- @azerupi for extensive documentation of `alt` and `alt_complete`
-+
-+### Breaking Changes
-+
-+- `escaped`, `separated_list` and `separated_nonempty_list` can now return `Incomplete` when necessary
-+- `InputIter` does not require `AsChar` on its `Item` type anymore
-+- the `core` feature that was putting nom in `no_std` mode has been removed. There is now a `std` feature, activated by default. If it is not activated, nom is in `no_std`
-+- in `verbose-errors` mode, the error list is now stored in a `Vec` instead of a box based linked list
-+- `chain!` has finally been removed
-+
-+### Changed
-+
-+- `Endianness` now implements `Debug`, `PartialEq`, `Eq`, `Clone` and `Copy`
-+- custom input types can now be cloned if they're not `Copy`
-+- the infamous 'Cannot infer type for E' error should happen less often now
-+- `str` is now available in `no_std` mode
-+
-+### Fixed
-+
-+- `FileProducer` will be marked as `Eof` on full buffer
-+- `named_args!` now has lifetimes that cannot conflict with the lifetimes from other arguments
-+
-+### Added
-+
-+- `be_u24`: big endian 24 bit unsigned integer parsing
-+- `IResult` now has a `unwrap_or` method
-+
-+
-+## 2.2.1 - 2017-04-03
-+
-+### Thanks
-+
-+- @Victor-Savu for formatting fixes in the README
-+- @chifflier for detecting and fixing integer overflows
-+- @utkarshkukreti for some performance improvements in benchmarks
-+
-+### Changed
-+
-+- when calculating how much data is needed in `IResult::Incomplete`, the addition could overflow (it is stored as a usize). This would apparently not result in any security vulnerability on release code
-+
-+## 2.2.0 - 2017-03-20
-+
-+### Thanks
-+
-+- @seppo0010 for fixing `named_args`
-+- @keruspe for implementing or() on `IResult`, adding the option of default cases in `switch!`, adding support for `cargo-travis`
-+- @timlyo for documentation fixes
-+- @JayKickliter for extending `hex_u32`
-+- @1011X for fixing regex integration
-+- @Kerollmops for actually marking `chain!` as deprecated
-+- @joliss for documentation fixes
-+- @utkarshkukreti for tests refactoring and performance improvement
-+- @tmccombs for documentation fixes
-+
-+### Added
-+
-+- `IResult` gets an `or()` method
-+- `take_until1`, `take_until_and_consume1`, `take_till1!` and `take_till1_s!` require at least 1 character
-+
-+### Changed
-+
-+- `hex_u32` accepts uppercase digits as well
-+- the character based combinators leverage the input traits
-+- the whitespace parsers now work on &str and other types
-+- `take_while1` returns `Incomplete` on empty input
-+- `switch!` can now take a default case
-+
-+### Fixed
-+
-+- `named_args!` now imports `IResult` directly
-+- the upgrade to regex 0.2 broke the regex combinators, they work now
-+
-+## 2.1.0 - 2017-01-27

-+- @DirkyJerky for documentation fixes
-+- @saschagrunert for documentation fixes
-+- @lucab for documentation fixes
-+- @hyone for documentation fixes
-+- @tstorch for factoring `Slice`
-+- @shepmaster for adding crate categories
-+- @antoyo for adding `named_args!`
-+
-+### Added
-+
-+- `verify!` uses a first parser, then applies a function to check that its result satisfies some conditions
-+- `named_args!` creates a parser function that can accept other arguments along with the input
-+- `parse_to!` will use the `parse` method from `FromStr` to parse a value. It will automatically translate the input to a string if necessary
-+- `float`, `float_s`, `double`, `double_s` can recognize floating point numbers in text
-+
-+### Changed
-+
-+- `escaped!` will now return `Incomplete` if needed
-+- `permutation!` supports up to 20 child parsers
-+
-+## 2.0.1 - 2016-12-10
-+
-+Bugfix release
-+
-+*Warning*: there is a small breaking change, `add_error!` is renamed to `add_return_error!`. This was planned for the 2.0 release but was forgotten. This is a small change in a feature that not many people use, for a release that is not yet widely in use, so there will be no 3.0 release for that change.
-+
-+### Thanks
-+
-+- @nickbabcock for catching and fixing the `add_error!` mixup
-+- @lucab for documentation fixes
-+- @jtdowney for noticing that `tag_no_case!` was not working at all for byte slices
-+
-+### Fixed
-+
-+- `add_error!` has been renamed to `add_return_error!`
-+- the `not!` combinator now accepts functions
-+- `tag_no_case!` is now working as accepted (before, it accepted everything)
-+
-+
-+## 2.0 - 2016-11-25
-+
-+The 2.0 release is one of the biggest yet. It was a good opportunity to clean up some badly named combinators and fix invalid behaviours.
-+
-+Since this version introduces a few breaking changes, an [upgrade documentation](https://github.com/Geal/nom/blob/master/doc/upgrading_to_nom_2.md) is available, detailing the steps to fix the most common migration issues. After testing on a set of 30 crates, most of them will build directly, a large part will just need to activate the "verbose-errors" compilation feature. The remaining fixes are documented.
-+
-+This version also adds a lot of interesting features, like the permutation combinator or whitespace separated formats support.
-+
-+### Thanks
-+
-+- @lu-zero for license help
-+- @adamgreig for type inference fixes
-+- @keruspe for documentation and example fixes, for the `IResult => Result` conversion work, making `AsChar`'s method more consistent, and adding `many_till!`
-+- @jdeeny for implementing `Offset` on `&str`
-+- @vickenty for documentation fixes and his refactoring of `length_value!` and `length_bytes!`
-+- @overdrivenpotato for refactoring some combinators
-+- @taralx for documentation fixes
-+- @keeperofdakeys for fixing eol behaviour, writing documentation and adding `named_attr!`
-+- @jturner314 for writing documentation
-+- @bozaro for fixing compilation errors
-+- @uniphil for adding a `crates.io` badge
-+- @badboy for documentation fixes
-+- @jugglerchris for fixing `take_s!`
-+- @AndyShiue for implementing `Error` and `Display` on `ErrorKind` and detecting incorrect UTF-8 string indexing
-+
-+### Added
-+
-+- the "simple" error management system does not accumulates errors when backtracking. This is a big perf gain, and is activated by default in nom 2.0
-+- nom can now work on any type that implement the traits defined in `src/traits.rs`: `InputLength`, `InputIter`, `InputTake`, `Compare`, `FindToken`, `FindSubstring`, `Slice`
-+- the documentation from Github's wiki has been moved to the `doc/` directory. They are markdown files that you can build with [cargo-external-doc](https://crates.io/crates/cargo-external-doc)
-+- whitespace separated format support: with the `ws!` combinator, you can automatically introduce whitespace parsers between all parsers and combinators
-+- the `permutation!` combinator applies its child parsers in any order, as long as they all succeed once, and return a tuple of the results
-+- `do_parse!` is a simpler alternative to `chain!`, which is now deprecated
-+- you can now transform an `IResult` in a `std::result::Result`
-+- `length_data!` parses a length, and returns a subslice of that length
-+- `tag_no_case!` provides case independent comparison. It works nicely, without any allocation, for ASCII strings, but for UTF-8 strings, it defaults to an unsatisfying (and incorrect) comparison by lowercasing both strings
-+- `named_attr!` creates functions like `named!` but can add attributes like documentation
-+- `many_till!` applies repeatedly its first child parser until the second succeeds
-+
-+### Changed
-+
-+- the "verbose" error management that was available in previous versions is now activated by the "verbose-errors" compilation feature
-+- code reorganization: most of the parsers were moved in separate files to make the source easier to navigate
-+- most of the combinators are now independent from the input type
-+- the `eof` function was replaced with the `eof!` macro
-+- `error!` and `add_error!` were replaced with `return_error!` and `add_return_error!` to fix the name conflict with the log crate
-+- the `offset()` method is now in the `Offset` trait
-+- `length_value!` has been renamed to `length_count!`. The new `length_value!` selects a slice and applies the second parser once on that slice
-+- `AsChar::is_0_to_9` is now `AsChar::is_dec_digit`
-+- the combinators with configurable endianness now take an enum instead of a boolean as parameter
-+
-+### Fixed
-+- the `count!`, `count_fixed!` and `length_*!` combinator calculate incomplete data needs correctly
-+- `eol`, `line_ending` and `not_line_ending` now have a consistent behaviour that works correctly with incomplete data
-+- `take_s!` didn't correctly handle the case when the slice is exactly the right length
-+

-+/// All the parsers must have the same return type.
-+///
-+/// If one of the parsers returns `Incomplete`, `alt!` will return `Incomplete`, to retry

-+///
-+/// The `alt!` combinator is used in the following way:
-+///
-+/// ```rust,ignore
-+/// alt!(parser_1 | parser_2 | ... | parser_n)
-+/// ```
-+///
-+/// # Basic example
-+///
-+/// ```
-+/// # #[macro_use] extern crate nom;
-+/// # fn main() {
-+/// // Create a parser that will match either "dragon" or "beast"
-+/// named!( dragon_or_beast, alt!( tag!( "dragon" ) | tag!( "beast" ) ) );

-+/// assert_eq!(result, b"beast");
-+/// assert_eq!(rest, b" of Gevaudan");
-+/// # }
-+/// ```
-+///
-+/// # Manipulate results
-+///
-+/// There exists another syntax for `alt!` that gives you the ability to
-+/// manipulate the result from each parser:
-+///
-+/// ```
-+/// # #[macro_use] extern crate nom;
-+/// # use nom::IResult::Done;

-+/// fn is_not_space(c: u8) -> bool { ! nom::is_space(c) }
-+///
-+/// // Our parser will return the `Dragon` variant when matching "dragon",

-+///
-+/// # Behaviour of `alt!`
-+///
-+/// **BE CAREFUL** there is a case where the behaviour of `alt!` can be confusing:
-+///
-+/// when the alternatives have different lengths, like this case:
-+///
-+/// ```ignore
-+/// named!( test, alt!( tag!( "abcd" ) | tag!( "ef" ) | tag!( "ghi" ) | tag!( "kl" ) ) );
-+/// ```
-+///
-+/// With this parser, if you pass `"abcd"` as input, the first alternative parses it correctly,
-+/// but if you pass `"efg"`, the first alternative will return `Incomplete`, since it needs an input
-+/// of 4 bytes. This behaviour of `alt!` is expected: if you get a partial input that isn't matched
-+/// by the first alternative, but would match if the input was complete, you want `alt!` to indicate
-+/// that it cannot decide with limited information.
-+///
-+/// There are two ways to fix this behaviour. The first one consists in ordering the alternatives
-+/// by size, like this:
-+///
-+/// ```ignore
-+/// named!( test, alt!( tag!( "ef" ) | tag!( "kl") | tag!( "ghi" ) | tag!( "abcd" ) ) );
-+/// ```
-+///
-+/// With this solution, the largest alternative will be tested last.
-+///
-+/// The other solution uses the `complete!` combinator, which transforms an `Incomplete` in an
-+/// `Error`. If one of the alternatives returns `Incomplete` but is wrapped by `complete!`,
-+/// `alt!` will try the next alternative. This is useful when you know that
-+/// you will not get partial input:
-+///
-+/// ```ignore
-+/// named!( test,
-+/// alt!(
-+/// complete!( tag!( "abcd" ) ) |
-+/// complete!( tag!( "ef" ) ) |
-+/// complete!( tag!( "ghi" ) ) |
-+/// complete!( tag!( "kl" ) )
-+/// )
-+/// );
-+/// ```
-+///
-+/// If you want the `complete!` combinator to be applied to all rules then use the convenience
-+/// `alt_complete!` macro (see below).
-+///
-+/// This behaviour of `alt!` can get especially confusing if multiple alternatives have different
-+/// sizes but a common prefix, like this:
-+///
-+/// ```ignore
-+/// named!( test, alt!( tag!( "abcd" ) | tag!( "ab" ) | tag!( "ef" ) ) );
-+/// ```
-+///
-+/// in that case, if you order by size, passing `"abcd"` as input will always be matched by the
-+/// smallest parser, so the solution using `complete!` is better suited.
-+///
-+/// You can also nest multiple `alt!`, like this:
-+///
-+/// ```ignore
-+/// named!( test,
-+/// alt!(
-+/// preceded!(
-+/// tag!("ab"),
-+/// alt!(
-+/// tag!( "cd" ) |
-+/// eof!()
-+/// )
-+/// )
-+/// | tag!( "ef" )
-+/// )
-+/// );
-+/// ```
-+///
-+/// `preceded!` will first parse `"ab"` then, if successful, try the alternatives "cd",
-+/// or empty input (End Of File). If none of them work, `preceded!` will fail and
-+/// "ef" will be tested.

-+//!
-+//! # What are parser combinators?
-+//!
-+//! Parser combinators are a way to build parsers out of small functions. instead of
-+//! writing a huge grammar file then generaing code, like you would do with lex and yacc,
-+//! you write small functions, to parse small things like a character, or a number,
-+//! and then you assemble them in larger and larger functions, that can parse larger
-+//! parts of your formats.
-+//!
-+//! You end up with a list of small functions that you can reuse everywhere you need. Each
-+//! of them can be unit tested anf fuzzed separately.
-+//!
-+//! # nom parser design
-+//!
-+//! All nom parsers follow the same convention. They are all functions with the following signature:
-+//!
-+//! ```ignore
-+//! fn parser(input: I) -> IResult<I,O> { ... }
-+//! ```
-+//!
-+//! Here is the definition of that `IResult` type:
-+//!
-+//! ```
-+//! # #[macro_use] extern crate nom;
-+//! # use nom::{Err,Needed};
-+//! # fn main() {}
-+//! pub enum IResult<I,O,E=u32> {
-+//! Done(I,O),
-+//! Error(Err<E>), // indicates the parser encountered an error. E is a custom error type you can redefine
-+//! /// Incomplete contains a Needed, an enum than can represent a known quantity of input data, or unknown
-+//! Incomplete(Needed) // if the parser did not have enough data to decide
-+//! }
-+//! ```
-+//!
-+//! What it means:
-+//!
-+//! * `Done(i,o)` means the parser was successful. `i` is the remaining part of the input, `o` is the correctly parsed value
-+//! The remaining part can then be used as input for other parsers called in a sequence
-+//! * `Error(e)` indicates the parser encountered an error. The `Err<E>` type is an enum of possible parser errors,
-+//! that can also contain a custom error that you'd specify, by redefining the `E` error type
-+//! * `Incomplete(i)` means the parser did not have enough information to decide, and tells you, if possible,
-+//! how much data it needs
-+//!
-+//! That way, you could write your own parser that recognizes the letter 'a' like this:
-+//!
-+//! ```
-+//! #[macro_use] extern crate nom;
-+//! use nom::{IResult,Needed,Err,ErrorKind};
-+//! # fn main() {}
-+//!
-+//! fn a(input: &[u8]) -> IResult<&[u8], char> {
-+//! // if there is not enough data, we return Ìncomplete
-+//! if input.len() == 0 {
-+//! IResult::Incomplete(Needed::Size(1))
-+//! } else {
-+//! if input[0] == 'a' as u8 {
-+//! // the first part of the returned value is the remaining slice
-+//! IResult::Done(&input[1..], 'a')
-+//! } else {
-+//! IResult::Error(error_code!(ErrorKind::Custom(42)))
-+//! }
-+//! }
-+//! }
-+//! ```
-+//!
-+//! Writing all the parsers manually, like this, is dangerous, despite Rust's safety features. There
-+//! are still a lot of mistakes one can make. That's why nom provides a list of macros to help in
-+//! developing parsers. As an example, here is a parser that would recognize the phrase
-+//! "Hello <someone>" and return the name of the person we hail:
-+//!
-+//! ```
-+//! #[macro_use] extern crate nom;
-+//! use nom::alpha;
-+//!
-+//! named!(hello, preceded!(tag!("Hello "), alpha));
-+//! # use nom::IResult;
-+//! # fn main() {
-+//! # assert_eq!(hello(b"Hello nom."), IResult::Done(&b"."[..], &b"nom"[..]));
-+//! # }
-+//! ```
-+//!
-+//! Let's deconstruct it:
-+//!
-+//! * `named!` generates a function with the correct type. Without `named` here, we could write the parser
-+//! as follows:
-+//!
-+//! ```
-+//! #[macro_use] extern crate nom;
-+//! use nom::{alpha,IResult};
-+//!
-+//! fn hello(input: &[u8]) -> IResult<&[u8], &[u8]> {
-+//! preceded!(input,
-+//! tag!("Hello "), alpha)
-+//! }
-+//! # fn main() {
-+//! # assert_eq!(hello(b"Hello nom."), IResult::Done(&b"."[..], &b"nom"[..]));
-+//! # }
-+//! ```
-+//!
-+//! By default, `named` makes a function that takes `&[u8]` as input type, and returns `&[u8]` as output type.
-+//! You can override it like this:
-+//!
-+//! * `named!(hello<&str>, ...):` would take `&[u8]` as input type, and return `&str` as output type.
-+//! * `named!(hello<&str, &str>, ...):` would take `&str` as input type, and return `&str` as output type.
-+//!
-+//! *Note* : when we don't use `named!`, we must pass the input as first argument of the top
-+//! level combinator (see the line `preceded!(input,` in the preceding code example). This is a macro trick
-+//! in nom to pass input from one combinator to the next by rewriting the call.
-+//!
-+//! Next part of the parser: `preceded!(tag!("Hello "), alpha))`. Here, `tag!` is a combinator that recognizes
-+//! a specific serie of bytes or characters. `alpha` is a function that recognizes alphabetical characters.
-+//! The `preceded!` combinator assembles them in a more complex parser: if both parsers are successful,
-+//! it returns the result of the second one (`alpha` is preceded by `tag!`).
-+//!
-+//! *Note* : combinators can assemble other combinators (macros), or parser functions, as long as they follow
-+//! the same interface. Here, `alpha` is a parser function already implemented in nom.
-+//!
-+//! # List of parsers and combinators
-+//!
-+//! ## Basic elements
-+//!
-+//! Those are used to recognize the lowest level elements of your grammar, like, "here is a dot", or
-+//! "here is an big endian integer".
-+//!
-+//! * **char!**: matches one character: `char!('a')` will make a parser that recognizes the letter 'a' (works with non ASCII chars too)
-+//! * **eof!**: `eof!()` returns its input if it is at the end of input data
-+//! * **is_a!, is_a_s!**: matches a sequence of any of the characters passed as arguments. `is_a!("ab1")` could recognize `ababa` or `1bb`. `is_a_s!` is a legacy combinator, it does exactly the same thing as `is_a`
-+//! * **is_not!, is_not_s!**: matches a sequence of none of the characters passed as arguments
-+//! * **one_of!**: matches one of the provided characters. `one_of!("abc")` could recognize 'a', 'b', or 'c'. It also works with non ASCII characters
-+//! * **none_of!**: matches anything but the provided characters
-+//! * **tag!, tag_s!**: recognizes a specific suite of characters or bytes. `tag!("hello")` matches "hello"
-+//! * **tag_no_case!**: recognizes a suite of ASCII characters, case insensitive. `tag_no_case!("hello")` could match "hello", "Hello" or even "HeLlO"
-+//! * **tag_no_case_s!** works like `tag_no_case` but on UTF-8 characters too (uses `&str` as input). Note that case insensitive comparison is not well defined for unicode, and that you might have bad surprises. Also, this combinator allocates a new string for the comparison. Ponder for a bit before using this combinator
-+//! * **take!, take_s!**: takes a specific number of bytes or characters. `take!(5)` would return "hello" from the string "hello world"
-+//! * **take_str!**: same as `take!` but returning a `&str`
-+//! * **take_till!, take_till_s!**: returns the longest list of bytes until the provided function succeeds. `take_till!(is_alphabetic)` with input "123abc" would return "123"
-+//! * **take_till1!, take_till1_s!**: same as `take_till!`, but the result must not be empty: `take_till1!(is_alphabetic)` would fail on "abc"
-+//! * **take_until!, take_until_s!**: returns the longest list of bytes until the provided tag is found. `take_until!("world")` with input "Hello world!" would return "Hello " and leave "world!" as remaining input
-+//! * **take_until1!**: same as `take_until!`, but cannot return an empty result
-+//! * **take_until_and_consume!, take_until_and_consume_s!**: same as `take_until!` but consumes the tag. `take_until_and_consume!("world")` with input "Hello world!" would return "Hello " and leave "!" as remaining input
-+//! * **take_until_and_consume1!**: same as `take_until_and_consume!`, but cannot return an empty result
-+//! * **take_until_either!**: returns the longest list of bytes until any of the provided characters are found
-+//! * **take_until_either_and_consume!**: same as `take_until_either!`, but consumes the terminating character
-+//! * **take_while!, take_while_s!**: returns the longest list of bytes for which the function is true. `take_while!(is_alphabetic)` with input "abc123" would return "abc"
-+//! * **take_while1!, take_while1_s!**: same as `take_while!`, but cannot return an empty result
-+//! * **value!**: you can use `value!` to always return the same result value without consuming input, like this: `value!(42)`. Or you can replace the result of a child parser with a predefined value, like this: `value!(42, tag!("abcd"))` which would replace, if successful, the return value from "abcd", to 42
-+//!
-+//! Parsing integers from binary formats can be done in two ways: with parser functions, or combinators with configurable endianness:
-+//!
-+//! * configurable endianness: **i16!, i32!, i64!, u16!, u32!, u64!** are combinators that take as argument a `nom::Endianness`,
-+//! like this: `i16!(endianness)`. If the parameter is nom::Endianness::Big, parse a big endian i16 integer, otherwise a little endian i16 integer
-+//! * fixed endianness: the functions are prefixed by "be_" for big endian numbers, and by "le_" for little endian numbers, and the suffix is the type they parse to. As an example, "be_u32" parses a big endian unsigned integer stored in 32 bits.
-+//! * **be_f32, be_f64, le_f32, le_f64**: recognize floating point numbers
-+//! * **be_i8, be_i16, be_i32, be_i24, be_i32, be_i64**: big endian signed integers
-+//! * **be_u8, be_u16, be_u32, be_u24, be_u32, be_u64**: big endian unsigned integers
-+//! * **le_i8, le_i16, le_i32, le_i24, le_i32, le_i64**: little endian signed integers
-+//! * **le_u8, le_u16, le_u32, le_u24, le_u32, le_u64**: little endian unsigned integers

--///
--/// **BE CAREFUL** there is a case where the behaviour of `alt!` can be confusing:
--///
--/// when the alternatives have different lengths, like this case:
--///
--/// ```ignore
--/// named!( test, alt!( tag!( "abcd" ) | tag!( "ef" ) | tag!( "ghi" ) | tag!( "kl" ) ) );
--/// ```
--///
--/// With this parser, if you pass `"abcd"` as input, the first alternative parses it correctly,
--/// but if you pass `"efg"`, the first alternative will return `Incomplete`, since it needs an input
--/// of 4 bytes. This behaviour of `alt!` is expected: if you get a partial input that isn't matched
--/// by the first alternative, but would match if the input was complete, you want `alt!` to indicate
--/// that it cannot decide with limited information.
--///
--/// There are two ways to fix this behaviour. The first one consists in ordering the alternatives
--/// by size, like this:
--///
--/// ```ignore
--/// named!( test, alt!( tag!( "ef" ) | tag!( "kl") | tag!( "ghi" ) | tag!( "abcd" ) ) );
--/// ```
--///
--/// With this solution, the largest alternative will be tested last.
--///
--/// The other solution uses the `complete!` combinator, which transforms an `Incomplete` in an
--/// `Error`. If one of the alternatives returns `Incomplete` but is wrapped by `complete!`,
--/// `alt!` will try the next alternative. This is useful when you know that
--/// you will not get partial input:
--///
--/// ```ignore
--/// named!( test,
--/// alt!(
--/// complete!( tag!( "abcd" ) ) |
--/// complete!( tag!( "ef" ) ) |
--/// complete!( tag!( "ghi" ) ) |
--/// complete!( tag!( "kl" ) )
--/// )
--/// );
--/// ```
--///
--/// If you want the `complete!` combinator to be applied to all rules then use the convenience
--/// `alt_complete!` macro (see below).
--///
--/// This behaviour of `alt!` can get especially confusing if multiple alternatives have different
--/// sizes but a common prefix, like this:
--///
--/// ```ignore
--/// named!( test, alt!( tag!( "abcd" ) | tag!( "ab" ) | tag!( "ef" ) ) );
--/// ```
--///
--/// in that case, if you order by size, passing `"abcd"` as input will always be matched by the
--/// smallest parser, so the solution using `complete!` is better suited.
--///
--/// You can also nest multiple `alt!`, like this:
--///
--/// ```ignore
--/// named!( test,
--/// alt!(
--/// preceded!(
--/// tag!("ab"),
--/// alt!(
--/// tag!( "cd" ) |
--/// eof
--/// )
--/// )
--/// | tag!( "ef" )
--/// )
--/// );
--/// ```
--///
--/// `preceded!` will first parse `"ab"` then, if successful, try the alternatives "cd",
--/// or empty input (End Of File). If none of them work, `preceded!` will fail and
--/// "ef" will be tested.

-+//! Error management
-+//!
-+//! there are two ways to handle errors in nom. The first one,
-+//! activated by default, uses the `nom::ErrorKind<E=u32>` enum
-+//! in the error branch of `IResult`. This enum can hold either
-+//! a parser specific error code, or a custom error type you
-+//! specify.
-+//!
-+//! If you need more advanced error management, you can activate
-+//! the "verbose-errors" compilation feature, which will give you
-+//! the error system available in nom 1.0. The verbose errors
-+//! accumulate error codes and positions as you backtrack through
-+//! the parser tree. From there, you can precisely identify which
-+//! parts of the input triggered the error case.
-+//!
-+//! Please note that the verbose error management is a bit slower
-+//! than the simple one.

-+//! Error management
-+//!

-+//! activated by default, uses the `nom::ErrorKind<E=u32>` enum
-+//! in the error branch of `IResult`. This enum can hold either
-+//! a parser specific error code, or a custom error type you
-+//! specify.
-+//!
-+//! If you need more advanced error management, you can activate
-+//! the "verbose-errors" compilation feature, which will give you
-+//! the error system available in nom 1.0. The verbose errors
-+//! accumulate error codes and positions as you backtrack through
-+//! the parser tree. From there, you can precisely identify which
-+//! parts of the input triggered the error case.
-+//!
-+//! Please note that the verbose error management is a bit slower
-+//! than the simple one.

-+//! Support for whitespace delimited formats
-+//!
-+//! a lot of textual formats allows spaces and other
-+//! types of separators between tokens. Handling it
-+//! manually with nom means wrapping all parsers
-+//! like this:
-+//!
-+//! ```ignore
-+//! named!(token, delimited!(space, tk, space));
-+//! ```
-+//!
-+//! To ease the development of such parsers, you
-+//! can use the whitespace parsing facility, which works
-+//! as follows:
-+//!
-+//! ```
-+//! # #[macro_use] extern crate nom;
-+//! # use nom::IResult::Done;
-+//! # fn main() {
-+//! named!(tuple<&[u8], (&[u8], &[u8]) >,
-+//! ws!(tuple!( take!(3), tag!("de") ))
-+//! );
-+//!
-+//! assert_eq!(
-+//! tuple(&b" \t abc de fg"[..]),
-+//! Done(&b"fg"[..], (&b"abc"[..], &b"de"[..]))
-+//! );
-+//! # }
-+//! ```
-+//!
-+//! The `ws!` combinator will modify the parser to
-+//! intersperse space parsers everywhere. By default,
-+//! it will consume the following characters: " \t\r\n".
-+//!
-+//! If you want to modify that behaviour, you can make
-+//! your own whitespace wrapper. As an example, if
-+//! you don't want to consume ends of lines, only
-+//! spaces and tabs, you can do it like this:
-+//!
-+//! ```
-+//! # #[macro_use] extern crate nom;
-+//! # use nom::IResult::Done;
-+//! named!(pub space, eat_separator!(&b" \t"[..]));
-+//!
-+//! #[macro_export]
-+//! macro_rules! sp (
-+//! ($i:expr, $($args:tt)*) => (
-+//! {
-+//! sep!($i, space, $($args)*)
-+//! }
-+//! )
-+//! );
-+//!
-+//! # fn main() {
-+//! named!(tuple<&[u8], (&[u8], &[u8]) >,
-+//! sp!(tuple!( take!(3), tag!("de") ))
-+//! );
-+//!
-+//! assert_eq!(
-+//! tuple(&b" \t abc de fg"[..]),
-+//! Done(&b"fg"[..], (&b"abc"[..], &b"de"[..]))
-+//! );
-+//! # }
-+//! ```
-+//!
-+//! This combinator works by replacing each combinator with
-+//! a version that supports wrapping with separator parsers.
-+//! It will not support the combinators you wrote in your
-+//! own code. You can still manually wrap them with the separator
-+//! you want, or you can copy the macros defined in src/whitespace.rs
-+//! and modify them to support a new combinator:
-+//! * copy the combinator's code here, add the _sep suffix
-+//! * add the `$separator:expr` as second argument
-+//! * wrap any sub parsers with sep!($separator, $submac!($($args)*))
-+//! * reference it in the definition of `sep!` as follows:
-+//!
-+//! ```ignore
-+//! ($i:expr, $separator:ident, my_combinator ! ($($rest:tt)*) ) => {
-+//! wrap_sep!($i,
-+//! $separator,
-+//! my_combinator_sep!($separator, $($rest)*)
-+//! )
