Calls 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:

RFCs

  • No calls for testing were issued this week.

Rust

  • No calls for testing were issued this week.

Rustup

  • No calls for testing were issued this week.

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.

Rust Compiler Performance Triage

2024-07-02 Triage Log

We saw a large set of primary benchmarks regress, mostly due to PR #120924 (lint_reasons and #[expect]) and PR #120639 (new effects desugaring). Separate from those, there are a couple rollup PRs (#127076, #127096) with some regressions that were limited to relatively few benchmarks; pnkfelix was unable to isolate a injecting PR that can be identified as a root cause (outside assistance welcome!).

Triage done by @pnkfelix. Revision range: c3d7fb39..cf2df68d

4 Regressions, 3 Improvements, 11 Mixed; 7 of them in rollups 59 artifact comparisons made in total
