Despite yet another week without suggestions, llogiq is appropriately pleased with his choice.

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. 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.

Quote of the Week

Just to provide another perspective: if you can write the programs you want to write, then all is good. You don't have to use every single tool in the standard library.

I co-authored the Rust book. I have twelve years experience writing Rust code, and just over thirty years of experience writing software. I have written a macro_rules macro exactly one time, and that was 95% taking someone else's macro and modifying it. I have written one proc macro. I have used Box::leak once. I have never used Arc::downgrade. I've used Cow a handful of times.

Don't stress yourself out. You're doing fine.

– Steve Klabnik on r/rust

Thanks to Jacob Finkelman for the suggestion!
