Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation 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!

The RFC style is now the default style in Rustfmt - try it out and let us know what you think!

We're currently writing up the discussions, we'd love some help. Check out the tracking issue for details.

Quote of the Week

When programmers are saying that there are a lot of bicycles in code that means that it contains reimplementations of freely available libraries instead of using them

Presumably the metric for this would be bicyclomatic complexity?

Thanks to Matt Ickstadt for the suggestion.
