Thanks to Kornel for the suggestion! Please submit your suggestions and votes for next week! Calls for Testing An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. If you are a feature implementer and would like your RFC to appear in this list, add a 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. Cargo Tracking Issue for trim-paths RFC 3127 Testing Instructions No calls for testing were issued this week by Rust, Rustup or Rust language RFCs. Let us know if you would like your feature to be tracked as a part of this list.
