Crate of the Week

This week's crate is grab, a command-line tool to quickly convert CSV to JSON.

Thanks to Gábor Maksa for the self-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.

No calls for testing were issued this week by Rust, Cargo, Rustup or Rust language RFCs.

Let us know if you would like your feature to be tracked as a part of this list.

Quote of the Week

What we collectively build, beyond the code artifacts that the compiler+tools are, is a group of people who come back, who learn, who share their understanding, who align their tastes, who take input from the community, etc etc. Merging an LLM-generated PR feeds only the “we have code that works” part of the Project; it’s not participating in all the other feedback cycles that make the project alive.

– Nadrieril on the Rust Project Perspectives on AI

Despite another week without a suggestion, llogiq is pleased with his choice.

Please submit quotes and vote for next week!
