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 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.
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.
No Calls for participation were submitted this week.
If you are a Rust project owner and are looking for contributors, please submit tasks here or through a PR to TWiR or by reaching out on X (formerly Twitter) or Mastodon!
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.

Please see the latest Who's Hiring thread on r/rust
... opaque number sequences (\<GitHub> "issue numbers") are not very informative about what is behind that pointer, and pretending they are is harmful. People could provide, instead, actual reasons for things, which do not require dereferencing random pointers, which thrashes cache.
Thanks to Anton Fetisov for the suggestion!
