Welcome to another issue of *This Week in Rust*, a weekly summary of Rust's progress and happenings in the community.
# What's cooking in master? 48 PRs were merged this week. ## Breaking changes - Slices are now represented as [number of elements, not number of bytes](https://github.com/mozilla/rust/pull/9885). - `fmt!` has been [completely removed](https://github.com/mozilla/rust/pull/9919). - Some fields in `std::comm` [have been made private](https://github.com/mozilla/rust/pull/9935). - `std::sys::refcount` [has been moved](https://github.com/mozilla/rust/pull/9922) to `std::managed::refcount`. - [A bunch of functions](https://github.com/mozilla/rust/pull/9896/files#diff-69196c6d2488bf8d5b3471084e854407L22) have moved from `std::sys` to `std::mem`. - `once fn` is [now a feature gate](https://github.com/mozilla/rust/pull/9863) rather than a `-Z` flag. - `Path` has been [completely rewritten](https://github.com/mozilla/rust/pull/9655). - `extra::flatpipes` [has been removed](https://github.com/mozilla/rust/pull/9886). ## Other changes - `jemalloc` has been [removed from the runtime](https://github.com/mozilla/rust/pull/9933). The [associated issue](https://github.com/mozilla/rust/issues/9925) is quite scary. - `rustdoc` [struct field visibility](https://github.com/mozilla/rust/pull/9946) is now corrected (it stripped fields where it should not have). - `rustdoc` also [uses the actual privacy rules](https://github.com/mozilla/rust/pull/9941) to strip methods. - `format!` now gives [much better](https://github.com/mozilla/rust/pull/9932) error messages for invalid format strings. - The `fmt::Default` trait, used for default formatting with `format!`, is [now documented](https://github.com/mozilla/rust/pull/9938). - `include_bin!` has been optimized, and the `k-nucleotides` benchmark now compiles [187x faster](https://github.com/mozilla/rust/pull/9851). - Vectors now have [`starts_with` and `ends_with` methods](https://github.com/mozilla/rust/pull/9907), which take slices. - An `abort` intrinsic [has been added](https://github.com/mozilla/rust/pull/9860). - Vectors now have a [`get_opt` method](https://github.com/mozilla/rust/pull/9608). ## New contributors A new section for new contributors! The new contributors this week are (as reported by git): - Chris Sainty - Eduard Burtescu - Erik Lyon - Harry Marr - Sébastien Chauvel - Vijay Korapaty - Ziad Hatahet - chitra # Weekly Meeting The [weekly meeting](https://github.com/mozilla/rust/wiki/Meeting-weekly-2013-10-15) discussed removing rusti, changing the attribute syntax, destructors in statics, and more multi-crate packages with rustpkg. # Announcements etc - Rust (and Servo) are participating in the [GNOME Outreach Program for Women](https://groups.google.com/forum/#!topic/mozilla.dev.servo/7kX_E0FlfkA). A bunch of people have already come into IRC about it. - <http://exercism.io> [is getting full Rust support](https://github.com/kytrinyx/exercism.io/pull/866). This is a very cool resource, and could help a lot getting newcomers acclimated. - [Unified Function/method Call Syntax and further simplification](https://mail.mozilla.org/pipermail/rust-dev/2013-October/006034.html). - [Safe Memory Management in Cyclone](http://www.reddit.com/r/rust/comments/1osbq2/safe_manual_memory_management_in_cyclone_research/). - [Audio](http://opensourcebridge.org/sessions/970) from Tim's talk in June is finally available! - An [OSdev](https://github.com/mozilla/rust/wiki/Operating-system-development) community has sprung up! The channel is `#rust-osdev`. - [Should I/O use conditions?](http://www.reddit.com/r/rust/comments/1omw47/should_io_use_conditions/). - [Pointers in Rust: A Guide](http://www.reddit.com/r/rust/comments/1opo36/pointers_in_rust_a_guide/). - I am on a [Rust hiatus](http://cmr.github.io/blog/2013/10/14/rust-hiatus/), for the time being. TWiR will still be happening, as you are reading it right now. - [rust-core](https://github.com/thestinger/rust-core) - A stub standard library. _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
