Crate of the Week

This week's crate is silkenweb, a library for building web apps with fine-grained reactivity and a clean separation of logic and UI.

Thanks to henrik for the suggestion!

Please submit your suggestions and votes for next week!

408 pull requests were merged in the last week

Rust Compiler Performance Triage

This week we have two sets of results as last week's arrived later than the publish date:

Triage done by @rylev and @simulacrum.

Revision range: b9832e72..650991d

Across both reports:

9 Regressions, 7 Improvements, 5 Mixed 127 artifact comparisons made in total

Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

Final Comment Period

Every week, the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now.

RFCs

Tracking Issues & PRs

Language Reference

Unsafe Code Guidelines

  • No Unsafe Code Guideline RFCs entered Final Comment Period this week.

New and Updated RFCs

  • No New or Updated RFCs were created this 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 RFCs issued a call for testing 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.

Quote of the Week

After doing a best fit, we found Rust projects were less likely to introduce vulnerabilities than their equivalent C++ projects at all relevant experience levels, but more importantly, we found the effect was most significant for first-time contributors, who were almost two orders of magnitude less likely to contribute vulnerabilities. That is, even though Rust may have a reputation as a harder language to learn, there is a very measurable effect that makes it better for newbies. Reviewers should not have to put as much effort into reviewing code to be confident that someone making their first foray into their project is accidentally adding a vulnerability.
