Title: This Week in Rust 542
Number: 542
Date: 2024-04-10
Category: This Week in Rust

Hello and welcome to another issue of *This Week in Rust*!
[Rust](https://www.rust-lang.org/) is a programming language empowering everyone to build reliable and efficient software.
This is a weekly summary of its progress and community.
Want something mentioned? Tag us at [@ThisWeekInRust](https://twitter.com/ThisWeekInRust) on Twitter or [@ThisWeekinRust](https://mastodon.social/@thisweekinrust) on mastodon.social, or [send us a pull request](https://github.com/rust-lang/this-week-in-rust).
Want to get involved? [We love contributions](https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md).

*This Week in Rust* is openly developed [on GitHub](https://github.com/rust-lang/this-week-in-rust) and archives can be viewed at [this-week-in-rust.org](https://this-week-in-rust.org/).

## Crate of the Week

<!-- COTW goes here -->

[Please submit your suggestions and votes for next week][submit_crate]!

[submit_crate]: https://users.rust-lang.org/t/crate-of-the-week/2704

## [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:

<!-- Calls for Testing go here, use this format:
* [<RFC Topic>](<RFC URL>)
* [Tracking Issue](<Tracking Issue URL>)
* [Testing steps](<Testing Steps URL>)
-->
<!-- or if there are no new or updated RFCs this week, use: * *No New or Updated RFCs were created this week.* -->
<!-- Remember to remove the `call-for-testing` label from the RFC so that the maintainer can signal for testers again, if desired. -->

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.

## Call for Participation; projects and speakers

### CFP - Projects

Always wanted to contribute to open-source projects but did not know where to start?
Every week we highlight some tasks from the Rust community for you to pick and get started!

Some of these tasks may also have mentors available, visit the task page for more information.

<!-- CFPs go here, use this format: * [project name - title of issue](link to issue) -->
<!-- * [ - ]() -->

If you are a Rust project owner and are looking for contributors, please submit tasks [here][guidelines].

[guidelines]: https://users.rust-lang.org/t/twir-call-for-participation/4821

### CFP - Speakers

Are you a new or experienced speaker looking for a place to share something cool? This section highlights events that are being planned and are accepting submissions to join their event as a speaker.

<!-- CFPs go here, use this format: * [**event name**](link to CFP)| Date CFP closes in YYYY-MM-DD | city,state,country | Date of event in YYYY-MM-DD -->
<!-- or if none - *No Calls for papers or presentations were submitted this week.* -->

### Rust Compiler Performance Triage

<!-- Perf results go here -->

### [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:

<!-- Approved RFCs go here, use this format: * [Topic](URL) -->
<!-- or if none were approved this week, use: * *No RFCs were approved this week.* -->
<!-- * []() -->

<!--
### [Approved Major Change Proposals (MCP)](https://forge.rust-lang.org/compiler/mcp.html)
<!~~ MCPs occur infrequently, so this section is commented out by default. ~~>
<!~~ MCPs which have been approved or rejected this week go here, use this format: * [major change accepted|rejected] [Topic](URL) ~~>
-->
