Crate of the Week

This week's Crate of the Week is alacritty, an OpenGL-propelled Terminal application. Really fast, nice looking. Missing scrollback. Thanks to Vikrant for the suggestion!

Submit your suggestions and votes for next week!

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:

Closed RFCs

Following proposals were rejected by the team after their 'final comment period' elapsed.

  • Abort by default v2. Specify abort-by-default in Cargo.toml when the user does cargo new --bin, as well as various other refinements to the panick strategy system.

New RFCs

No new RFCs were proposed this week.

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!

Ready for PR:

There's a lot of them right now, contributions here would be very welcome. If you want advice or help getting started, please ping nrc, or any other member of the style team, in #rust-style.

Quote of the Week

I really hate the phrase "fighting". Calling it a fight doesn't do justice to the conversations you have with the borrow checker when you use Rust every day. You don't fight with the borrow checker, because there isn't a fight to win. It's far more elegant, more precise. It's fencing; you fence with the borrow checker, with ripostes and parries and well-aimed thrusts. And sometimes, you get to the end and you realize you lose anyway because the thing you were trying to do was fundamentally wrong. And it's okay, because it's just fencing, and you're a little wiser, a little better-honed, a little more practiced for your next bout.
