Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safe, concurrent, and fast. This is a weekly summary of its progress and community. Want something mentioned? Send me an email! Want to get involved? We love contributions.

This Week in Rust is openly developed on Github. If you find any errors or omissions in this week's issue, please submit a PR.

This week the mailing list was closed, std::io was renamed std::old_io. There were many pull requests merged, but not a lot of churn.

What's cooking on master?

143 pull requests were merged in the last week, and 6 RFCs.

Flavio, Steve and Alex all made rollups. Thanks!

Now you can follow breaking changes as they happen!

Breaking Changes

  • The Show and String formatting traits have been renamed to Debug and Display to more clearly reflect their related purposes. Automatically getting a string conversion to use with format!("{:?}", something_to_debug) is now written #[derive(Debug)].
  • Both the #[start] and #[main] attributes are feature gated as a precaution. Use #![feature(start)] and #![feature(main)] to get them back.
