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!.

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:

• Add support for naked functions.
• Expand the current pub/non-pub categorization of items with the ability to say "make this item visible solely to a (named) module tree".
• Add octet-oriented interface to std::net::Ipv6Addr.
• Unix socket support in the standard library.
• Implement a method, contains(), for Range, RangeFrom, and RangeTo, checking if a number is in the range..
• Add a replace_slice method to Vec<T> and String which removes a range of elements, and replaces it in place with a given sequence of values.

New RFCs

• Saturating and checking integer wrapper types.
• Stabilize the -C overflow-checks command line argument.
• Revise type ascription operator to use type equality, not coercion.
• Add TryFrom and TryInto traits.
• Add more integer atomic types.

Upcoming Events
