Title: This Week in Rust 46
Date: 2014-04-26 14:06
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).
This issue combines this week and last, since I was very busy with school last
week, and did not have time to write.
<!-- more -->
# What's cooking on master?
153 pull requests were merged in the last two weeks.
## Breaking Changes
- Auto-rooting of `@` [has been
removed](https://github.com/mozilla/rust/pull/13559). The exact fallout of
this isn't obvious to me, but presumably this makes some uses of `@` not
work.
- `std::task::task` [has been
renamed](https://github.com/mozilla/rust/pull/13675) to `TaskBuilder::new`.
- Closures can [no longer be
applied](https://github.com/mozilla/rust/pull/13686) through a `&`-pointer.
This fixes some memory unsafety.
- The `Round` trait [has been
removed](https://github.com/mozilla/rust/pull/13597), and is now part of
`Float`, and `Float` now takes things by-value.
- `Unsafe<T>` [is now always
`Share`](https://github.com/mozilla/rust/pull/13583), regardless of whether
or not the contained type is `Share`.
- Modulo (`%` operator) on float types [has been
removed](https://github.com/mozilla/rust/pull/13410), use the `rem` method
instead.
- `~[T]` [is no longer growable](https://github.com/mozilla/rust/pull/13588).
- Some `Bitv` method names [have
changed](https://github.com/mozilla/rust/pull/13572).
- The `priv` keyword [is no longer
used](https://github.com/mozilla/rust/pull/13547), but is still reserved.
- Some cases where destructors were not run [have been
fixed](https://github.com/mozilla/rust/pull/13390).
- `unwrap` and `unwrap_err` on `Result` [now require the wrapper type to
implement `Show`](https://github.com/mozilla/rust/pull/13479).
- Some return types in `std::comm` [have been made
consistent](https://github.com/mozilla/rust/pull/13448).
## Other Changes
- There is now a [pure-Rust regular expression
library](https://github.com/mozilla/rust/pull/13700) in the standard
library. As I've come to expect from burntsushi, the docs are fantastic.
- [Unix sockets](https://github.com/mozilla/rust/pull/13723) and [TCP
sockets](https://github.com/mozilla/rust/pull/13688) now support accept with
a timeout. [TcpStream::connect](https://github.com/mozilla/rust/pull/13604) can also
take a timeout.
- [64-bit Windows is now partially
supported](https://github.com/mozilla/rust/pull/13692). Unwinding still
doesn't work.
- `&&` [is now parsed as `& &`](https://github.com/mozilla/rust/pull/13576)
when appropriate.
- Errors about use of moved values [are much nicer
now](https://github.com/mozilla/rust/pull/13418).
- Cloning vectors [is now much much
faster](https://github.com/mozilla/rust/pull/13539).
- SipHash [has also been
optimized](https://github.com/mozilla/rust/pull/13522).
- Steve Klabnik's 30 minute introduction to Rust [has been added as official
documentation](https://github.com/mozilla/rust/pull/13416).

# Weekly Meeting
- [Two weeks
ago](https://github.com/mozilla/rust/wiki/Meeting-weekly-2014-04-15), a
bunch of RFCs were discussed, as well as a breaking change log.
- [Last week], some more RFCs were discussed, notably the regex crate, numeric
type inference, and disableable asserts.
# RFCs
- [Linker placement attribute](https://github.com/rust-lang/rfcs/pull/44)
- [Avoiding integer overflow](https://github.com/rust-lang/rfcs/pull/45)
- [Writer size hints](https://github.com/rust-lang/rfcs/pull/46)
- [Revised trait matching](https://github.com/rust-lang/rfcs/pull/48)
- [Disableable assertions](https://github.com/rust-lang/rfcs/pull/50)
- [Macro name resolution](https://github.com/rust-lang/rfcs/pull/51)
- [Private trait items](https://github.com/rust-lang/rfcs/pull/52)
- [Coroutines](https://github.com/rust-lang/rfcs/pull/53)
# Community Updates
- For all Mac users, there is now
[dash-rust](https://github.com/indirect/dash-rust/), for Rust API docs in
Dash.
- Another [Rust By Example](http://rustbyexample.github.io/) has been created.
This one is much more complete and also looks pretty nice.
- [Teepee](http://chrismorgan.info/blog/introducing-teepee.html) has been
announced, the successor to `rust-http`.
- [zinc](https://mail.mozilla.org/pipermail/rust-dev/2014-April/009618.html),
a bare-metal Rust stack.
- [An IntelliJ Rust plugin](https://github.com/Vektah/idea-rust).
- [Rust for C++
Programmers](http://featherweightmusings.blogspot.co.nz/search/label/rust-for-c).
- [A very fast n-queens solver](https://github.com/reem/rust-n-queens).
