This is a weekly summary of its progress and +community. Want something mentioned? [Send me an +email!](mailto:corey@octayn.net?subject=This%20Week%20in%20Rust%20Suggestion) +Want to get involved? [We love +contributions](https://github.com/mozilla/rust/wiki/Note-guide-for-new-contributors). + +<!-- more --> + +# What's cooking on master? + +66 pull requests were merged this week. + +## Breaking Changes + +- Some more string methods [now return +Option](https://github.com/mozilla/rust/pull/12797). +- Matching on `~str` [has been +removed](https://github.com/mozilla/rust/pull/12756). +- IO iterators [now yield +IoResult](https://github.com/mozilla/rust/pull/12414). +- The channel types and constructor [have been +renamed](https://github.com/mozilla/rust/pull/12815). `Chan` is now `Sender`, +`Port` is now `Receiver`, and `Chan::new` is now `std::comm::channel`. +- `std::cmp::{min, max}` [now require +TotalOrd](https://github.com/mozilla/rust/pull/12869). For floats, use +`a.min(b)`. +- The handling of `cfg(not(a, b))` [has changed +slightly](https://github.com/mozilla/rust/pull/12893). +- `libextra` [has finally been +purged](https://github.com/mozilla/rust/pull/12896). + +## Other Changes + +- Another great PR from the illustrious ktt3ja, the compiler [will now give +suggestions](https://github.com/mozilla/rust/pull/12238) on how to fix +lifetime woes. This is an awesome usability improvement. +- Implementations of `Deref` and `DerefMut` [are now +considered](https://github.com/mozilla/rust/pull/12610) for automatic +dereferencing. +- Partial type hints [are now +implemented](https://github.com/mozilla/rust/pull/12764), but not at the item +level (in function returns etc). The eventual goal is to have +`some_iter.collect::<Vec<_>>()` be possible. +- There is a [new +guide](http://static.rust-lang.org/doc/master/guide-unsafe.html) for "low level and unsafe code". +[PR](https://github.com/mozilla/rust/pull/12887). +- There is now a lint for [uses of +`~[T]`](https://github.com/mozilla/rust/pull/12861). It's very verbose. The +replacement for `~[T]`, as recommended by the lint, is `std::vec_ng::Vec<T>`. +It implements almost everything `~[T]` does. +- `HashMap` [has been +reimplemented](https://github.com/mozilla/rust/pull/12081) to use [Robin Hood +hashing](http://codecapsule.com/2013/11/11/robin-hood-hashing/). It's now much +more faster, and uses less space. +- Support for basic backtracing [has been +reimplemented](https://github.com/mozilla/rust/pull/12602). +- `char` [now has simple case +folding](https://github.com/mozilla/rust/pull/12561). That is, basic +locale-ignorant case conversion. +- Inline assembly [now supports the `+` +modifier](https://github.com/mozilla/rust/pull/12798). +## New Contributors + +- Adolfo Ochagavía +- Clark Gaebel +- Peter Marheine +- Piotr Czarnecki +- Piotr Zolnierek +- Robert Gawdzik + +# Weekly Meeting + +The [weekly +meeting](https://github.com/mozilla/rust/wiki/Meeting-weekly-2014-03-11) +discussed the new hashmap, destructuring the `self` argument, partial type +hints, coercion of returned values, as well as the requirements of unsafe +pointers and the continued existence of `*mut`. + +# This Week in Servo + +Servo is a web browser engine written in Rust and is one of the primary test +cases for the Rust language. + +In the last two weeks, we landed 56 PRs. + +## Notable additions + +- Patrick Walton made fixes to ACID in +[#1905](https://github.com/mozilla/servo/pull/1905) +- Along with about 20 other PRs, ms2ger brought WindowTimers up to date with +the spec in [#1890](https://github.com/mozilla/servo/pull/1890) +- Pradeep Kumar implemented `position:absolute` in +[#1681](https://github.com/mozilla/servo/pull/1681) and fixed up relative +positioning in [#1808](https://github.com/mozilla/servo/pull/1808) +- Bill Yang fixed up our instructions for installation on Ubuntu Linux in +[#1881](https://github.com/mozilla/servo/pull/1881) +- Bruno Abinader fixed up HTMLCollection in +[#1838](https://github.com/mozilla/servo/pull/1838) +- Isabelle Carter ensured that children of `position:fixed` items make it into +the correct DisplayList in [#1832](https://github.com/mozilla/servo/pull/1832) +- Manish Goregaokar made `getElementsByName` return a `NodeList` in +[#1756](https://github.com/mozilla/servo/pull/1756) +- Keegan McAllister cleaned up our reftest harness and made them test both the +CPU and GPU rendering paths in +[#1804](https://github.com/mozilla/servo/pull/1804) + +## New contributors + +- Bill Yang (analyst74) +- Manish Goregaokar (manishearth) + +## Meetings and Notes + +At this week's +[meeting](https://github.com/mozilla/servo/wiki/Meeting-2014-03-10), we +discussed HTML parsing, embedding, writing modes, the ACID2 burndown, and the +Rust upgrade. + +# RFCs + +[We have a new RFC +process](https://github.com/rust-lang/rfcs/blob/master/active/0001-rfc-process.md)! +Every week I'll list the new RFCs and RFCs that have been accepted. +Contributing to the discussions around these RFCs is the easiest way to drive +the design of Rust. + +As an aside, I will no longer include any RFCs in the "Announcements" section +that are not sent to the RFC repository. + +- [Private Fields by Default](https://github.com/rust-lang/rfcs/pull/1) +- [Rearchitecting the attribute-usage lint](https://github.com/rust-lang/rfcs/pull/3) +- [Unified Function Call Syntax](https://github.com/rust-lang/rfcs/pull/4) +- [Virtual Structs](https://github.com/rust-lang/rfcs/pull/5) +- [Add OsUnknown as a target operating system](https://github.com/rust-lang/rfcs/pull/7) +- [Redesign Compiler Intrinsics](https://github.com/rust-lang/rfcs/pull/8) +- ["Fat Objects" for DSTs](https://github.com/rust-lang/rfcs/pull/9), an +alternative to "Virtual Structs". + +# Project Updates + +[rust-bencode](https://github.com/arjantop/rust-bencode), a pure Rust +implementation of Bencode encoding. +[Bencode](http://en.wikipedia.org/wiki/Bencode) is used primarily in the +BitTorrent protocol.

It utilizes the recent overloadable deref to do optional +initialization before returning the reference to the wrapped type. It's an +example that the right amount of abstractions, but syntactic (macros) and +semantic (operator overloading) can reduce boilerplate for a more pleasant +experience. + +[Racer](https://github.com/phildawes/racer) - code completion for Rust. This +project is in its early stages, but can already do a fair bit of useful +completion. It is not using the parser (libsyntax) or compiler (librustc), so +it will likely always be inaccurate in some respect. Nevertheless, this may +prove to be an incredibly useful tool. + +[QuickCheck for Rust](https://github.com/BurntSushi/quickcheck). This has some +seriously great docs. QuickCheck, originally from Haskell, is a way of doing +property-based testing. You describe certain properties your code should have +and it generates random inputs, trying to find inputs that violate those +properties. This is a modern, featureful port of QuickCheck and hopefully gets +even more useful as time goes on. + +The [coreutils port](https://github.com/uutils/coreutils) is still alive and +making progress. 32 out of 119 programs are implemented. This is a great +project to contribute to if you want a relatively self-contained, +goal-oriented task.
