Welcome to another issue of *This Week in Rust!* This week marks the addition of some more feature gates, removal of `std::io`, and some feature proposals.
# What's cooking on master? 47 PRs were merged this week, and we passed issue number 10000. ## Breaking Changes - Most of the crypto in the stdlib [has been removed](https://github.com/mozilla/rust/pull/9744). - `std::io` [has been removed](https://github.com/mozilla/rust/pull/9901), with corresponding improvements in `std::rt::io`. - The `frame_address` intrinsic [has been removed](https://github.com/mozilla/rust/pull/10040). - `@`-ptrs are [now feature-gated](https://github.com/mozilla/rust/pull/9923), reflecting the fact that they will exist in a very different form once they are finished. - All of the logging that used `fmt` (`debug!` and so forth) [have been transitioned to `format!`](https://github.com/mozilla/rust/pull/10006). - `asm!` [is also featured gated](https://github.com/mozilla/rust/pull/10009). - `sys::log_str` [has moved](https://github.com/mozilla/rust/pull/9937). ## Other changes - The long-awaited addition of `mut` in patterns [has finally happened](https://github.com/mozilla/rust/pull/10026). `let (mut x, y) = (1, 2);` works. - The scheduler now uses [lock free data structures](https://github.com/mozilla/rust/pull/10080), which are supposed to perform much better. - The homing code [now does less work](https://github.com/mozilla/rust/pull/10070), which does one third as many `write`'s. - `stdout` [is now buffered](https://github.com/mozilla/rust/pull/10060). - A [non-libuv event loop](https://github.com/mozilla/rust/pull/10054) has been added. - `std::rand` has seen [more](https://github.com/mozilla/rust/pull/9810) [work](https://github.com/mozilla/rust/pull/10015). - `rustpkg` [now supports arbitrary dependencies](https://github.com/mozilla/rust/pull/9654), such as C libraries. - `mut` is [now allowed on self](https://github.com/mozilla/rust/pull/9989). - Nested comments [are now allowed](https://github.com/mozilla/rust/pull/9936). - `rustpkg` will now [find crates in the current directory], so you can say `rustpkg build` in a source dir and it will build in a workspace. - Some new float intrinsics [have been exposed](https://github.com/mozilla/rust/pull/9986). - `println!` [allocates less](https://github.com/mozilla/rust/pull/9979). ## New contributors - Igor Bukanov - Mark Rowe - Michael Letterle - reedlepee # Announcements etc - There will be a [meetup](http://www.meetup.com/Rust-Bay-Area/events/143439552/) in the San Fransisco Mozilla office. Patrick Walton will be talking about sprocketnes. If you're in the area, you should definitely go! - [rust-ci](http://hiho.io/rust-ci/) has been created, which lets you have travis automatically rebuild and test your repo daily, to reduce language/library breakage. - [rust-mustache](https://github.com/erickt/rust-mustache) and [rust-zmq](https://github.com/erickt/rust-zmq) have been updated for master. - [Short talk about Rust at Scala.IO in Paris (October 25th)](http://www.reddit.com/r/rust/comments/1pdrv6/short_talk_about_rust_at_scalaio_in_paris_october/). - [A Bit of Functional Programming in Rust, or A Misguided First Look at Rust for ML Programmers](http://www.reddit.com/r/rust/comments/1pe2lc/a_bit_of_functional_programming_in_rust_or_a/). - [A draft proposal for single inheritance](http://www.reddit.com/r/rust/comments/1p52tj/a_draft_proposal_for_single_inheritance_in_rust/). - [Iterators yielding mutable references](http://www.reddit.com/r/rust/comments/1p4vnk/iterators_yielding_mutable_references/). - [Servo transitions from libcss to a new CSS library written in Rust](http://www.reddit.com/r/rust/comments/1p4qeh/servo_transitions_from_libcss_to_a_new_css/). - [On stack safety](http://www.reddit.com/r/rust/comments/1owhwi/on_stack_safety/). _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
