Thanks to Edoardo Morandi for the suggestion!

Please submit your suggestions and votes for next week!

Call 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:

  • 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

Even though the summary might not look like it, this was actually a relatively quiet week, with a few small regressions. The large regression that is also shown in the summary table was caused by extending the verification of incremental compilation results. However, this verification is not actually fully enabled by default, so these regressions are mostly only visible in our benchmarking suite, which enables the verification to achieve more deterministic benchmarking results. One small regression was also caused by enabling frame pointers for the Rust standard library, which should improve profiling of Rust programs.

Triage done by @kobzol. Revision range: e919669d..21d94a3d

Quote of the Week

In 10 years we went from “Rust will never replace C and C++” to “New C/C++ should not be written anymore, and you should use Rust”. Good job.
