## Crate of the Week
This week's crate is [type\_description](https://crates.io/crates/type_description), a crate to make types discoverable for users by explaining them in a way that a user can understand without knowing implementation details.
Thanks to [musicmatze](https://users.rust-lang.org/t/crate-of-the-week/2704/1119) for the suggestion!
[Please submit your suggestions and votes for next week][submit_crate]!

### Rust Compiler Performance Triage
Noise continues to make triaging a bit tedious. We've become good at identifying noise, but we may need to invest in trying to reduce it or automate some of the triaging needed to identify it. In terms of performance, this week ending up being positive albeit with improvements only outweighing regressions by a little. Some of the largest improvements were in reverts of previous regressions as well.
Triage done by **@rylev**.
Revision range: [629a414d..822f8](https://perf.rust-lang.org/?start=629a414d7ba4caa3ca28b0a46c478e2ecb4c0059&end=822f8c22f540b12f296d844ad5bf39aaa47bfeb4&absolute=false&stat=instructions%3Au)

### [Call for Testing](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing)
An important step for RFC implementation is for people to experiment with the
implementation and give feedback, especially before stabilization. The following
RFCs would benefit from user testing before moving forward:
* [Have `cargo publish` block until crate is published](https://github.com/rust-lang/cargo/issues/9507#issuecomment-1296058029)
If you are a feature implementer and would like your RFC to appear on the above list, add the new `call-for-testing`
label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature
need testing.
### [Approved RFCs](https://github.com/rust-lang/rfcs/commits/master)
Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These
are the RFCs that were approved for implementation this week:
* *No RFCs were approved this week.*
### Final Comment Period

# Quote of the Week
> I'm getting more convinced that Rust code is generally going to end up faster than C++ code every day I work on optimizations.
>
> Strong immutability and no-alias guarantees are a game-changer and we've only really begun to scratch the surface of what can be done.
