Hello and welcome to another issue of This Week in Rust! Rust 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 on Twitter or @ThisWeekinRust on mastodon.social, or send us a pull request. Want to get involved? We love contributions.
Arc<Mutex<T>>- Katharina Fey
This week's crate is man-in-the-middle-proxy, a - surprise! - man in the middle proxy.
Thanks to Emanuele Em for the self-suggestion!
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.
If you are a Rust project owner and are looking for contributors, please submit tasks here.
376 pull requests were merged in the last week

generate_functionto generate in different local crate
replace_or_with_or_elseassists more generally applicable
A really quiet week with almost all regressions being due to noise in benchmarks that show "bimodality" in codegen that can cause swings in performance from one change to the other. The only true performance change was a two-line change by @nnethercote to remove a redundant function call which led to a 0.3% improvement in performance across roughly 15 benchmarks.
Triage done by @rylev. Revision range: 31f858d9..8f9e09ac

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:
Every week, the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now.
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:
If you are a feature implementer and would like your RFC to appear on the above list, add the new
label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature

(…) as much as i dislike the cargo-geiger concept, the name … kind of works
unsafeis a lot like uranium. it’s just one more metal ore you can process, refine, and machine. it doesn’t combust in atmosphere, it doesn’t corrode or make weird acids. unless you go out of your way to make it dangerous you don’t even have to worry about critical masses. you can work with it pretty normally most of the time
but if you don’t know exactly what it is, what it does, and how to work with it, it will cause mysterious illnesses that only crop up long after you’ve stopped touching it
Thanks to Stephan Sokolow for the suggestion!
