Hello and welcome to another issue of This Week in Rust! Rust 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! Want to get involved? We love contributions.
This Week in Rust is openly developed on GitHub. If you find any errors or omissions in this week's issue, please submit a PR.
The big news
Rust 1.0.0-alpha.2 was released on Friday, but keep using nightlies. Six more weeks until the beta, which should become 1.0. Only six more weeks.
What's cooking on master?
157 pull requests were merged in the last week, and 15 RFC PRs.
Now you can follow breaking changes as they happen!
- A variety of tweaks have been made to
std::threadbefore declaring it stable.
vec!macro accepts a new form,
vec![element; len], which produces a vector containing a number of clones of the same element.
CStringtype has seen a few modifications, as well as the introduction of the
IntoIteratornow has an associated type for specifying the element type.
ExactSizeIteratoris no longer implemented for 64-bit ranges.
- In target specs,
target-word-sizeis now called
target-pointer-width, to match the recently changed
fmt::Writerwas renamed to
isuffixes are now replaced with
- A number of modules have been audited
for incorrect use of
- Use of arbitrary attributes not defined by the language is feature gated.
Sendno longer requires
'static, which make it possible to express various data-parallel scenarious by sharing interior pointers. RFC.
- The 'Macros' chapter of TRPL has been overhauled and a new 'Advanced Macros' chapter added.
rustc --versionnow reports the build date in addition to the commit date, to make it more clear what nightly you are on.
- Florian Hahn added a new category of 'parse-fail' tests to the test suite. This makes it easier to compare model parsers to the production parser.

Friend of the Tree
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'.
This week's friend of the tree was ... Toby Scrace.
"Today I would like to nominate Toby Scrace as Friend of the Tree. Toby emailed me over the weekend about a login vulnerability on crates.io where you could log in to whomever the previously logged in user was regardless of whether the GitHub authentication was successful or not. I very much appreciate Toby emailing me privately ahead of time, and I definitely feel that Toby has earned becoming Friend of the Tree."
