Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safety, concurrency, and speed. This is a weekly summary of its progress and community. Want something mentioned? Tweet us at @ThisWeekInRust or send us a pull request. Want to get involved? We love contributions.

This Week in Rust is openly developed on GitHub. If you find any errors in this week's issue, please submit a PR.

Approved RFCs

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

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

New RFCs

Style RFCs

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!

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.

brson on Refactoring std for ultimate portability.

Thanks to Japaric for the suggestion.
