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

Extend entry API to work on borrowed keys.

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.

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 jimmycuadra:

dtolnay for outstanding work on Serde, taking it from a great library into an outstanding library, improving documentation significantly, being on top of the macros 1.1 transition, and even developing a new high level library for making custom derive under macros 1.1 easier to work with. sgrif for outstanding work on Diesel, an ORM that will change the game for ORMs, and for being incredibly helpful and friendly with early adopters.

From nmatsakis:

I nominate TimNN for Friend of the Forest for his repeated and invaluable work minimizing and bisecting (example). Keep up the good work!

From dzamlo:

I'd like to nominate BurntSushi for Friend of the Forest. I think the multiples crates he contributed are both important and high quality. In addition to his code contributions to the ecosystem, he also did some good and informative write up about some of them.

From pmarcelll:

I'd like to nominate GuillaumeGomez for the "Rust documentation superhero" title as well.

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