Title: This Week in Rust 83
Date: 2015-06-15
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:
safety, concurrency, and speed. 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/rust-lang/rust/wiki/Note-guide-for-new-contributors).
*This Week in Rust* is openly developed [on GitHub](https://github.com/cmr/this-week-in-rust).

Now you can follow breaking changes *[as they happen][BitRust2]*!
[BitRust2]: http://killercup.github.io/bitrust/
# Breaking Changes
* [Prevent raw pointers from being used as explicit
self](https://github.com/rust-lang/rust/pull/26225). Probably nobody
has ever tried to write such code, and the current implemented
behavior is bonkers.
# Other Changes
* [Add `Result::expect`](https://github.com/rust-lang/rust/pull/25359/files).
* [Add
`CString::from_ptr/into_ptr`](https://github.com/rust-lang/rust/pull/25777). For
transfering ownership of C strings across the FFI.
* [Implement `str::split_at`](https://github.com/rust-lang/rust/pull/25839).
* [Stabilize a number of new `fs` features](https://github.com/rust-lang/rust/pull/25844).
* [Parallel code generation works
again](https://github.com/rust-lang/rust/pull/26018). Pass `rustc -C
codegen-units=4` to try.
* [The `to_uppercase` and `to_lowercase` functions now support complex
case mapping](https://github.com/rust-lang/rust/pull/26039). This
changes the behavior of the *stable*
`char::to_uppercase/to_lowercase` and also stabilizes
`str::to_uppercase/to_lowercase`.
* [Implement `Extend<&T> where: T: Copy` for a variety of collection
types](https://github.com/rust-lang/rust/pull/25989).
* [The unstable `String::from_str` is
deprecated](https://github.com/rust-lang/rust/pull/26077). Use
`String::from`.
* [Heuristics for detecting identifier typos are improved](https://github.com/rust-lang/rust/pull/26087).

# Approved RFCs
* [RFC 1105. Policy on API
evolution](https://github.com/rust-lang/rfcs/blob/master/text/1105-api-evolution.md). Describes
how the Rust project evaluates changes to the libraries, and which are allowed when.
* [RFC 1119. `Result::expect`](https://github.com/rust-lang/rfcs/pull/1119).
* [RFC 1122. Semantic
versioning](https://github.com/rust-lang/rfcs/blob/master/text/1122-language-semver.md). Describes
how the language itself is allowed to change.
* [RFC 1123. Introduce `str::split_at`](https://github.com/rust-lang/rfcs/blob/master/text/1123-str-split-at.md)
* [RFC 1131. `likely` intrinsic](https://github.com/rust-lang/rfcs/blob/master/text/1131-likely-intrinsic.md). For hinting hot and cold branches.
# New RFCs
* [Adjust default object
bounds](https://github.com/rust-lang/rfcs/pull/1156). This fixes some
dumb rules that made it into 1.0, but is a breaking change that
affects relatively little code.
* [Expand the `std::net` module](https://github.com/rust-lang/rfcs/pull/1158).
# Upcoming Events

# Quote of the Week
```text
<Quxxy> I had a fun one in cargo script: there's currently no way in Rust
to get a file's mtime and the system time in the same time format
<Quxxy> (On Windows)
<Quxxy> You can get one in UNIX time, the other in Windows time
<Quxxy> Which have different scales and different epochs
<Quxxy> Rust: Buy Your Own Damn Batteries; What Are You, A Communist?

Now you can follow breaking changes *[as they happen][BitRust2]*!
[BitRust2]: http://killercup.github.io/bitrust/
# Breaking Changes
* [Don't panic when stdout doesn't
exist](https://github.com/rust-lang/rust/pull/26168). See [RFC
1014](https://github.com/rust-lang/rfcs/blob/master/text/1014-stdout-existential-crisis.md). This
is breaking because it changes the behavior of stdio, but in ways
that are expected to be less surprising. Considered a bugfix.
# Other Changes
* Thanks to Ashesh Kumar for pointing out that rust-lang.org was not
configured with DMARC to prevent spoofing. The misconfiguration has
now been corrected.
* [Optimize implementations of FromIterator and Extend for
Vec](https://github.com/rust-lang/rust/pull/22681).
* [Result - Add an `expect` method that prints a message and the `Err`
value](https://github.com/rust-lang/rust/pull/25359).
* [Break apart global unstable
features](https://github.com/rust-lang/rust/pull/26192). Some of the
catch-all feature names, `core`, `std_misc`, `collections`, `alloc`,
are split into smaller, better-named features.
* The regex crate received a [rewrite that includes a big performance
improvement](https://github.com/rust-lang/regex/pull/91).
* [Avoid deref/ref cycles for no-op conversions between unsafe
pointers](https://github.com/rust-lang/rust/pull/26336). Reduces the
amount of IR rustc generates.
* [Pass fat pointers in two immediate
arguments](https://github.com/rust-lang/rust/pull/26411). More
codegen improvements from dotdash.
* [Add FromRaw{Fd,Handle,Socket} to os
preludes](https://github.com/rust-lang/rust/pull/26413).
* [Custom Debug impl for
io::Error](https://github.com/rust-lang/rust/pull/26416).
# New Contributors
* David Stygstra
* Gulshan Singh
* Jake Hickey
* joliv
* Markus
* Steven Walter
* Yongqian Li
# Approved RFCs
* [Update RFC 195 to account for RFC
246](https://github.com/rust-lang/rfcs/pull/865). Just accounting
for the `const`/`static` distinction in the associated items RFC.
* [Clarify cast rules, especially regarding fat
pointers](https://github.com/rust-lang/rfcs/pull/1052). Updates RFC
401: coercions.
* [RFC 1156: Adjust default object
bounds](https://github.com/rust-lang/rfcs/blob/master/text/1156-adjust-default-object-bounds.md). This
is a stable breaking change (the first) to the default lifetime
bounds of trait objects.

# What's cooking on nightly?
122 pull requests were [merged in the last week][merged].
[merged]: https://github.com/issues?q=is%3Apr+org%3Arust-lang+is%3Amerged+merged%3A2015-07-06..2015-07-13
* [bluss](https://github.com/bluss) updated [substring search to use the Two Way algorithm](https://github.com/rust-lang/rust/pull/26327).
* [1.2 beta will issue warnings about code that will break](https://github.com/rust-lang/rust/pull/26829) when [RFC 1156](https://github.com/rust-lang/rfcs/blob/master/text/1156-adjust-default-object-bounds.md) is implemented. This approved breaking change will fix a major wart and is thought to break no real code.
* [Linux installation will try harder to set up the dynamic linker](https://github.com/rust-lang/rust-installer/pull/41), fixing a bad first-run issue where Fedora systems can't run rustc out of the box.
* The `#[prelude_import]` attribute, which is employed by rustc to perform [dark](https://github.com/rust-lang/rust/blob/6a3b385cbd6b9044b4447da96aad066e8b257ddf/src/libsyntax/std_inject.rs#L164) and [mysterious](https://github.com/rust-lang/rust/blob/6a3b385cbd6b9044b4447da96aad066e8b257ddf/src/librustc_resolve/build_reduced_graph.rs#L292-L294) acts, but is not supposed to be stable. This is not known to break real code.
* `rustc` on Windows now [looks in the registry](https://github.com/rust-lang/rust/pull/26741) to find the location of the MSVC linker.
* Inspired by some [poor I/O performance on the forums](https://users.rust-lang.org/t/reading-from-stdin-performance/2025), bluss dug into the problem [and pulled out some big improvements in zero-filling](https://github.com/rust-lang/rust/pull/26849) that greatly improve the performance of `Vec::resize` and `Read::read_to_end`.
* GuillaumeGomez [added a host](https://github.com/rust-lang/rust/pull/26742) of [new error explanations](https://github.com/rust-lang/rust/pull/26879).
* dotdash got some [huge improvements in the performance of `PartialEq` for slices](https://github.com/rust-lang/rust/pull/26884).
* `rustc` now uses [LLVM to write archive files where possible](https://github.com/rust-lang/rust/pull/26926). Eventually this will eliminate the compiler's dependency on the `ar` utility.
* [Add `String::into_boxed_slice` and `Box<str>::into_string`](https://github.com/rust-lang/rust/pull/26931).
* Dave Huseby added [initial support for FreeBSD on i686](https://github.com/rust-lang/rust/pull/26959). Rust has long worked on 64-bit FreeBSD.
* Simon [updated the gedit syntax highlighter](https://github.com/rust-lang/gedit-config/pull/8).

[bors](https://github.com/bors) underwent a [sudden unscheduled
upgrade](https://internals.rust-lang.org/t/buildbot-is-down-for-a-bit/2365/4)
this week, incurring unusual amounts of downtime. Thankfully, [Manish
crafted an epic rollup](https://github.com/rust-lang/rust/pull/27066)
to make up some of the slack.
98 pull requests were [merged in the last week][merged].

* [LLVM was updated to
3.7](https://github.com/rust-lang/rust/pull/27076). Includes
improved 32-bit MSVC, archive writing, and some performance
improvements and minor fixes.

# Approved RFCs
Changes to Rust follow the Rust [RFC (request for comments)
process](https://github.com/rust-lang/rfcs#rust-rfcs). These
are the RFCs that were approved for implementation this week:
* [RFC for creation of `IntoRaw{Fd, Socket, Handle}` trait to
complement
`AsRaw*`](https://github.com/rust-lang/rfcs/pull/1174). This
provides interop between the standard library's I/O and other
out-of-tree platform-specific APIs.

# Friend of the Tree
[The Rust Team](http://www.rust-lang.org/team.html) likes to
occasionally recognize people who have made
outstanding contributions to The Rust Project, its ecosystem, and its
community. These people are 'friends of the tree'.
[This week's friend of the tree](https://internals.rust-lang.org/t/subteam-reports-2015-07-24/2397) was @tshepang.
Over the last year Tshepang has landed over 100 improvements to our documentation. Tshepang saw where documentation was not, and said "No. This will not do."
We should all endeavor to care about docs as much as Tshepang.
# Subteam reports
Every week [The Rust Teams](http://www.rust-lang.org/team.html)
release a report on what is going on in their corner of the
project. Here are the highlights from [this week's
report](https://internals.rust-lang.org/t/subteam-reports-2015-07-24/2397/2).
* The compiler is being refactored to work on an HIR and an MIR.
* Work is proceeding on stabilizing the core library.
* Basic allocators will soon be available.
* MSVC integration is proceeding rapidly.

[merged]: https://github.com/issues?q=is%3Apr+org%3Arust-lang+is%3Amerged+merged%3A2015-07-27..2015-08-03
* Gankro landed [The Advanced Rust Programming
Language](https://github.com/rust-lang/rust/pull/27032), which was
quickly renamed to [The
Rustonomicon](https://github.com/rust-lang/rust/pull/27444). This
book is about unsafe Rust and will become Gankro's master's
thesis. [Read it
online](http://doc.rust-lang.org/nightly/adv-book/).
* [Nonzeroing move
hints](https://github.com/rust-lang/rust/pull/26173). This patch
adds drop flags to the stack as part of the [non-zeroing drop
RFC](https://github.com/rust-lang/rfcs/blob/master/text/0320-nonzeroing-dynamic-drop.md). It
does not yet remove the drop flag from objects.
* [@azerupi](http://github.com/azerupi) cleaned up the design of
gitbook, the tool that generates The Book.
* [Deprecated
`VecMap`](https://github.com/rust-lang/rust/pull/26734). This
little-used unstable collection has been moved to the `vec_map`
crate.
* [Deprecate a number of unstable
features](https://github.com/rust-lang/rust/pull/26914). The list is
sizable.
* [Implement `Clone` for `Box<[T]> where T:
Clone`](https://github.com/rust-lang/rust/pull/26934)
* [Make `AtomicPtr` `Send`](https://github.com/rust-lang/rust/pull/27052)
* [Make `Rc` and `Arc` `mem::forget`
safe](https://github.com/rust-lang/rust/pull/27174). This closes
some corner-case soundness holes in reference counting.
* [More extended errors!](https://github.com/rust-lang/rust/pull/27230).
* [Add a `--cap-lints` flag to the
compiler](https://github.com/rust-lang/rust/pull/27260). This flag
[will be used by Cargo to avoid breaking dependencies when lints
change](https://github.com/rust-lang/rfcs/blob/master/text/1193-cap-lints.md).
* [Rewrite dropck to be more
correct](https://github.com/rust-lang/rust/pull/27261).
* [Improve SipHash performance for longer
data](https://github.com/rust-lang/rust/pull/27280).
* [Stabilize a number of small
APIs](https://github.com/rust-lang/rust/pull/27370).
* [Implement `Clone` for
`Box<str>`](https://github.com/rust-lang/rust/pull/27371).
* [Gate associated type
defaults](https://github.com/rust-lang/rust/pull/27382). 1.1 stable
mistakenly allowed default associated types to be written, but their
use was completely broken. With other outstanding questions about
the feature it has been gated for 1.2.

# Subteam reports
Every week [The Rust Team](http://www.rust-lang.org/team.html) release
a report on what is going on in their corner of the project. Here are
the highlights from [this week's report](https://internals.rust-lang.org/t/subteam-reports-2015-08-07/2473).
## Libs team
[Full report](https://github.com/rust-lang/subteams/blob/master/libs/reports/2015-08-07.md)
First off, we had a great RustCamp last weekend! As many of us were
involved with the event, it was a bit of a slow week.
Decisions from last week:
- [RFC PR #1184](https://github.com/rust-lang/rfcs/pull/1184):
RFC: Stabilize the #![no_std] attribute
- Merged
- [RFC PR #1183](https://github.com/rust-lang/rfcs/pull/1183):
RFC: Allow changing the default allocator
- Merged
- [RFC PR #770](https://github.com/rust-lang/rfcs/pull/770):
io error handling design
- Closed
- [RFC PR #980](https://github.com/rust-lang/rfcs/pull/980):
read_exact
- Merged
- [RFC PR #1194](https://github.com/rust-lang/rfcs/pull/1194):
RFC: Add item recovery collection APIs
- To be merged, pending last bits of bikeshedding
- [PR #26818](https://github.com/rust-lang/rust/pull/26818):
Stabilize duration (with renamings)
- Merge, need to decide about 1.3 backport
We'd like to call attention to the following two policy RFCs:
- [PR #1242](https://github.com/rust-lang/rfcs/pull/1242):
RFC: policy for rust-lang crates
- [PR #1224](https://github.com/rust-lang/rfcs/pull/1224):
Update the RFC process with sub-teams, amongst other things.
as well as an RFC relating to `catch_panic` and exception safety in Rust:
- [PR #1236](https://github.com/rust-lang/rfcs/pull/1236):
RFC: Stabilize catch_panic
This week's RFCs going into (or staying in) **final comment period**:
- [FCP PR #1195](https://github.com/rust-lang/rfcs/pull/1195):
ordered query API
- [FCP PR #1192](https://github.com/rust-lang/rfcs/pull/1192):
RFC for inclusive ranges with ...
## Lang team
[Full report](https://github.com/rust-lang/subteams/blob/master/lang/reports/2015-08-07.md)
The following RFCs are being promoted to **final comment period**:
- [PR #886](https://github.com/rust-lang/rfcs/pull/886): Permit
`#[must_use]` attributes on functions as well as types. This allows
for functions whose return value should not be ignored even if the
type of that value is unexceptional (e.g., the `ok()` method of
`Result`).
- [PR #890](https://github.com/rust-lang/rfcs/pull/890): Custom
preludes. This RFC proposes an extension that allows crates to
define their own preludes. This can be used to have common names
available throughout a crate without forcing them to be explicitly
imported everywhere. This is particularly useful when combined with
the convention of having external crates define a `pub mod prelude`
that downstream crates can import into their own local
preludes. While clearly convenient, there were some concerns raised
that this will give rise to multiple dialects of Rust.
- [PR #953](https://github.com/rust-lang/rfcs/pull/953): This defines
traits to support `+=` and other operators, closing a gap in our
operator overloading support. The traits take the LHS via an `&mut`
reference to permit in-place updates, take the RHS by value, and do
not require that the `Add` trait also be implemented.
- [PR #1135](https://github.com/rust-lang/rfcs/pull/1135): This PR
permits raw fat pointers (e.g., `*[i32]` or `*Trait`) to be
compared, just like raw thin pointer (e.g., `*i32`). The semantics
are to compare both the pointer itself *and* any accompanying data
(e.g., the length of the slice).
- [PR #1189](https://github.com/rust-lang/rfcs/pull/1189): This PR
simply corrects typos.
The following two RFCs have been accepted:
- [PR #1214](https://github.com/rust-lang/rfcs/pull/1214): Clarify
(and improve) rules for projections and well-formedness.
- [PR #1219](https://github.com/rust-lang/rfcs/pull/1219): Allow
aliasing imports when importing as a group.
In addition, I would like to call attention to the following RFC:
- [PR #1238](https://github.com/rust-lang/rfcs/pull/1238):
Nonparametric dropck. This RFC simplifies the dropck rules to close
some soundness holes and make room for specialization. The change is
expected to cause little to no breakage in practice, e.g., a crater
run found no affected crates, but it nonetheless affects a core
component of the language.
## Compiler team
[Full report](https://github.com/rust-lang/subteams/blob/master/compiler/reports/2015-08-07.md)
@arielb1 opened
[PR #27551](https://github.com/rust-lang/rust/pull/27551), which
changes how structs and enums are represented in the compiler,
replacing various hashtables with a single `AdtDef` struct. This is a
reimplementation of a similar PR by @aatch. In addition to cleaner
code, it results in a small performance boost (approximately 5%).
There has been some progress towards removing drop flags. @pnkfelix
landed his "nonzeroing move hints" branch
([PR #26173](https://github.com/rust-lang/rust/pull/26173)). Unfortunately,
some critical bugs were found shortly thereafter. The fix
([PR #27413](https://github.com/rust-lang/rust/pull/27413)) is not yet
ready.

# Quote of the Week
```
<bluss> I've tried using unchecked indexing in non-trivial code now a couple of times. It never makes a big difference
<bluss> Profiling shows like 1-2% improvement if that
<bluss> so it's the tightest loops you should worry about, not much more
```
@bluss knows a few things about micro-optimization.
Thanks to @bluss for the tip. [Submit your quotes for next week!][submit].
