Title: This Week in Rust 47
Date: 2014-05-05 14:26
Category: This Week in Rust
Hello and welcome to another issue of *This Week in Rust*!
[Rust](http://rust-lang.org) 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!](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).

# What's cooking on master?
45 pull requests were merged this week.
## Breaking Changes
- `~"foo"` and `&"bar"` literals [have been removed from the
language](https://github.com/mozilla/rust/pull/13877). The second is a noop
and the first is replaced by `"foo".to_owned()`.
- The various `rev_iter` methods [have been
removed](https://github.com/mozilla/rust/pull/13648) in favor of making more
iterators implement `DoubleEndedIterator`. See the commit messages for more
details.
## Other Changes
- The first part of [opt-in built-in
traits](https://github.com/rust-lang/rfcs/blob/master/active/0003-opt-in-builtin-traits.md)
[has landed](https://github.com/mozilla/rust/pull/13868). The built-in
traits can now be explicitly implemented and derived.
- There is [now a lint](https://github.com/mozilla/rust/pull/13579) for
negating `uint` values.
- There is [now a `debug_assert`
macro](https://github.com/mozilla/rust/pull/13789) for assertions which can
be compiled out.
- There is [now a `bitflags`
macro](https://github.com/mozilla/rust/pull/13072) for generating a nice
bitflag API.
- `serialize` [now has a streaming JSON
parser](https://github.com/mozilla/rust/pull/12740).
- We now use `-ffunction-sections`, `-fdata-sections`, and `--gc-sections`,
[for a 67% size reduction](https://github.com/mozilla/rust/pull/13833) of
hello world on Linux.

# 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 week, we landed 28 PRs.
## Notable additions
- Lars Bergstrom landed the Rust upgrade, bringing Servo in line with April
10th Rust in [#2238](https://github.com/mozilla/servo/pull/2238)
- Patrick Walton re-enabled parallel layout in
[#2174](https://github.com/mozilla/servo/pull/2174) and added parallel
display list building in [#2235](https://github.com/mozilla/servo/pull/2235)
- jgraham updated the Web Platform Tests integration to support passing some
arguments via. env variables in
[#2245](https://github.com/mozilla/servo/pull/2245)
- ms2ger rewrote the handling of optional arguments in
`getJSToNativeConversionTemplate` in
[#2244](https://github.com/mozilla/servo/pull/2244)
- Matt Brubeck cleaned up another dynamic borrow failure leading to pipeline
problems in [#2252](https://github.com/mozilla/servo/pull/2252)
- Jack Moffitt cleaned up some of our Makefile and autoconf files in
[#2232](https://github.com/mozilla/servo/pull/2232)
- Gulshan Singh fixed `TimeStamp` to return the actual time in
[#2275](https://github.com/mozilla/servo/pull/2275)
- Mike Blumenkrantz added the start of embedding support in
[#2257](https://github.com/mozilla/servo/pull/2257)

## Meetings and Notes
In this week's
[meeting](https://github.com/mozilla/servo/wiki/Meeting-2014-04-28), we
introduced three new team members. Brendan (bjz) is a long-time Rust developer
here on a Mozilla internship. Glenn Watson (gw) is a full-time member of the
Servo team, with an initial focus on platform features. And Manish Goregaokar
will be participating in Google Summer of Code, working on XMLHttpRequest. We
covered the JS rooting changes, timing of the next Rust upgrade, the status of
Web Platform Tests, and the use of prebuilt Rust compiler binaries.
