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.

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!

Friends of the Forest

Our community likes to recognize people who have made outstanding contributions to the Rust Project, its ecosystem, and its community. These people are 'friends of the forest'.

This week's friends of the forest are:

From AtheMathmo:

I'd like to nominate bluss for his work on scientific programming in Rust. ndarray is a monumental project but in addition to that he has worked (really) hard to share that knowledge among others and provided easy-to-use libraries like matrixmultiply. Without bluss' assistance rulinalg would be in a far worse state.

From nasa42:

I'd like to nominate Yehuda Katz, the lord of package managers.

Submit your Friends-of-the-Forest nominations for next week!
