Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:
No RFCs were approved this week!
Final Comment Period
Style RFCs are part of the process for deciding on style guidelines for the Rust community and defaults for Rustfmt. The process is similar to the RFC process, but we try to reach rough consensus on issues (including a final comment period) before progressing to PRs. Just like the RFC process, all users are welcome to comment and submit RFCs. If you want to help decide what Rust code should look like, come get involved!
Ready for PR:
Final comment period:
- 11/9. Rust Boulder/Denver Monthly Meeting.
- 11/10. Columbus Rust Society.
- 11/14. Seattle Rust Meetup.
- 11/15. Rust Philippines: Introduction to Rust Programming Language.
- 11/16. Rust User Group Cologne - Open Source Audio Meetup.
- 11/16. London Rust meetup #10.
- 11/16. Rust LA Monthly Meetup - Hack Night.

Quote of the Week
I want to paint you a picture of a utopia in which Rust has expanded to become the fabric of the entire classical computing world, where the possibilities of what we can achieve are not shackled to the decaying dreams of computer science past. In this perfect utopia you have invented the perfect model for managing your computer's sci-fi hardware, perfectly free from the legacy of Unix and Windows. And you need the perfect language to write it in. Everywhere you look is legacy: C, C++, Java; the stacks get bigger and bigger, cruft all the way down.
The only shining light is Rust. Those Rustaceans have been chipping away the cruft, distilling their platform to only the essence of bits and bytes, while also expanding its expressive power toward legendary elegance. Rust doesn't want to tell you how to build your system. Rust wants to serve you, to fulfill your dreams, on your terms. For your ambitions, Rust is the only reasonable choice in a world filled with compromises.
Thanks to Japaric for the suggestion.
