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
- [disposition: merge] Finalize syntax and parameter scoping for
impl Trait, while expanding it to arguments.
- [disposition: merge] extend
?to operate over other types.
- [disposition: merge] Specify
- [disposition: close] Add Cargo post-build scripts.
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!
We're making good progress and the style is coming together. If you want to see the style in practice, check out our example or use the Integer32 Playground and select 'Proposed RFC' from the 'Format' menu. Be aware that implementation is work in progress.
Issues in final comment period:
- Spaces around
- Return type on new line - proposed to close
- Attribute/doc comment ordering
- Ordering of types of groups within a module
- Function calls and chains of calls
- Combining opening and closing delims
- Where clauses
Good first issues:
