[mikael]

Summary

Announce: https://blog.rust-lang.org/2022/08/11/Rust-1.63.0.html
ChangeLog: https://github.com/rust-lang/rust/releases/tag/1.63.0

Test Plan

These ports are broken (packed_simd has to be updated), I'll put the patch in bugzilla
mail/thunderbird
www/firefox-esr
games/veloren
textproc/ripgrep

14amd64: ok
12aarch64: ok
13powerpc64le: ok

Add jbeich@ and gecko@ since the patch in the PR touches their port (games/veloren, www/firefox-esr, mail/thunderbird)

I'm not sure if src/bootstrap/lib.rs is correctly updated...

veloren-rust-1.63.diff4 KBDownload

Please, merge (squash) veloren fix with the update instead of landing separately. lazy::OnceCell -> cell::OnceCell rename requires a conditional if supporting both 1.62 and 1.63 is desired. Otherwise, applying the patch breaks rust < 1.63 until lang/rust is updated.

error[E0433]: failed to resolve: could not find `OnceCell` in `cell`

What's different from the patch in PR 265915 ? https://bz-attachments.freebsd.org/attachment.cgi?id=235976
phabricator is incredibly hard to use...

Patch comment and avoiding cfg-if noise. I didn't notice otherwise.

Well, you've requested review here and not on bugzilla.
