Title: This Week in Rust 70

Category: This Week in Rust
4+
5+
Hello and welcome to another issue of *This Week in Rust*!
6+
[Rust](http://rust-lang.org) is a systems language pursuing the trifecta:
7+
safety, concurrency, and speed. This is a weekly summary of its progress and
8+
community. Want something mentioned? [Send me an
9+
email!](mailto:[email protected]?subject=This%20Week%20in%20Rust%20Suggestion)
10+
Want to get involved? [We love
11+
contributions](https://github.com/rust-lang/rust/wiki/Note-guide-for-new-contributors).
12+
13+
*This Week in Rust* is openly developed [on GitHub](https://github.com/cmr/this-week-in-rust).
14+
If you find any errors or omissions in this week's issue, [please submit a PR](https://github.com/cmr/this-week-in-rust/pulls).

# What's cooking on master?
17+
18+
127 pull requests were [merged in the last week][merged], and 18 [RFC PRs][rfcs].

26+
27+
## Breaking Changes
28+
29+
* In types that implement `Drop`, [lifetimes must outlive the
30+
value][drop]. This will soon make it possible to safely implement
31+
`Drop` for types where `#[unsafe_destructor]` is now required. Read
32+
the [gorgeous RFC][drop-rfc] for details.
33+
* The reserved keyword `be`, for invoking guaranteed tail calls, [has
34+
been replaced with `become`][be], but `be` will remain in our
35+
hearts. [RFC][be-rfc].
36+
* [`Self` is a keyword][Self].
37+
* `#[unsafe_no_drop_flag]` is now under the
38+
[`unsafe_no_drop_flag`][flag] feature gate.
39+
* [Some float constants were renamed][float].
40+
* [`std::failure` moved to `std::panicking`][fail]. This is an
41+
unstable module dealing with unwinding, not likely to cause
42+
breakage.
43+
44+
[be]: https://github.com/rust-lang/rust/pull/21918
45+
[be-rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0601-replace-be-with-become.md
46+
[drop]: https://github.com/rust-lang/rust/pull/21972
47+
[drop-rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0769-sound-generic-drop.md
48+
[Self]: https://github.com/rust-lang/rust/pull/22158
49+
[flag]: https://github.com/rust-lang/rust/pull/22178

[float]: https://github.com/rust-lang/rust/pull/22254
51+
[fail]: https://github.com/rust-lang/rust/pull/22347
52+
53+
## Other Changes
54+
55+
* Objects now have [default lifetime bounds][obj], so you don't have
56+
to write `Box<Trait+'static>` when you don't care about storing
57+
references. [RFC][obj-rfc].
58+
* The new [`std::fs`][fs] and [`std::process`][proc] modules have arrived! They are much the
59+
same as the old but follow new conventions as described in [RFC 579] and [RFC 739].
60+
* On Unix Rust will soon be [uninstallable][un] by running
61+
`/usr/local/lib/rustlib/uninstall.sh`.
62+
* Richo Healey added lints for putting `#[no_mangle]` on [`const`s, as well as on private `static`s][no_mangle]. `#[no_mangle]` only makes sense for things with public symbol names.
63+
* eddyb endured an [epic struggle][epic] with @bors to make borrows of constants `&'static`.

# Friend of the Tree
93+
94+
The Rust Team likes to occassionally recognize people who have made outstanding contributions to The Rust Project, its ecosystem, and its community. These people are 'friends of the tree'.
95+
96+
This week's friend of the tree was ... Jonathan Reem (reem)
97+
98+
[Jonathan Reem] has been making an impact on Rust since May 2014. His primary contribution has been as the main author of the prominent Iron web framework, though he has also created several other popular projects including the testing framework stainless. His practical experience with these projects has led to several improvements in upstream Rust, most notably his complete rewrite of the TaskPool type. Reem is doing everything he can to advance the Rust cause.
