# Contributing to Rust
|
|
|
|
Thank you for your interest in contributing to Rust! There are many ways to
|
|
contribute, and we appreciate all of them. This document is a bit long, so here's
|
|
links to the major sections:
|
|
|
|
* [Feature Requests](#feature-requests)
|
|
* [Bug Reports](#bug-reports)
|
|
* [Pull Requests](#pull-requests)
|
|
* [Writing Documentation](#writing-documentation)
|
|
* [Issue Triage](#issue-triage)
|
|
* [Out-of-tree Contributions](#out-of-tree-contributions)
|
|
|
|
If you have questions, please make a post on [internals.rust-lang.org][internals] or
|
|
hop on [#rust-internals][pound-rust-internals].
|
|
|
|
As a reminder, all contributors are expected to follow our [Code of Conduct][coc].

## Feature Requests
|
|
|
|
To request a change to the way that the Rust language works, please open an
|
|
issue in the [RFCs repository](https://github.com/rust-lang/rfcs/issues/new)
|
|
rather than this one. New features and other significant language changes
|
|
must go through the RFC process.
|
|
|
|
## Bug Reports
|
|
|
|
While bugs are unfortunate, they're a reality in software. We can't fix what we
|
|
don't know about, so please report liberally. If you're not sure if something
|
|
is a bug or not, feel free to file a bug anyway.
|
|
|
|
If you have the chance, before reporting a bug, please [search existing
|
|
issues](https://github.com/rust-lang/rust/search?q=&type=Issues&utf8=%E2%9C%93),
|
|
as it's possible that someone else has already reported your error. This doesn't
|
|
always work, and sometimes it's hard to know what to search for, so consider this
|
|
extra credit. We won't mind if you accidentally file a duplicate report.
|
|
|
|
Opening an issue is as easy as following [this
|
|
link](https://github.com/rust-lang/rust/issues/new) and filling out the fields.
|
|
Here's a template that you can use to file a bug, though it's not necessary to
|
|
use it exactly:
|
|
|
|
<short summary of the bug>
|
|
|
|
I tried this code:
|
|
|
|
<code sample that causes the bug>
|
|
|
|
I expected to see this happen: <explanation>
|
|
|
|
Instead, this happened: <explanation>
|
|
|
|
## Meta
|
|
|
|
`rustc --version --verbose`:
|
|
|
|
Backtrace:
|
|
|
|
All three components are important: what you did, what you expected, what
|
|
happened instead. Please include the output of `rustc --version --verbose`,
|
|
which includes important information about what platform you're on, what
|
|
version of Rust you're using, etc.
|
|
|
|
Sometimes, a backtrace is helpful, and so including that is nice. To get
|
|
a backtrace, set the `RUST_BACKTRACE` environment variable. The easiest way
|
|
to do this is to invoke `rustc` like this:
|
|
|
|
```bash
|
|
$ RUST_BACKTRACE=1 rustc ...
|
|
```
|
|
|
|
## Pull Requests
|
|
|
|
Pull requests are the primary mechanism we use to change Rust. GitHub itself
|
|
has some [great documentation][pull-requests] on using the Pull Request
|
|
feature. We use the 'fork and pull' model described there.
|
|
|
|
[pull-requests]: https://help.github.com/articles/using-pull-requests/
|
|
|
|
Please make pull requests against the `master` branch.
|
|
|
|
All pull requests are reviewed by another person. We have a bot,
|
|
@rust-highfive, that will automatically assign a random person to review your request.
|
|
|
|
If you want to request that a specific person reviews your pull request,
|
|
you can add an `r?` to the message. For example, Steve usually reviews
|
|
documentation changes. So if you were to make a documentation change, add
|
|
|
|
r? @steveklabnik
|
|
|
|
to the end of the message, and @rust-highfive will assign @steveklabnik instead
|
|
of a random person. This is entirely optional.
|
|
|
|
After someone has reviewed your pull request, they will leave an annotation
|
|
on the pull request with an `r+`. It will look something like this:
|
|
|
|
@bors: r+ 38fe8d2
|
|
|
|
This tells @bors, our lovable integration bot, that your pull request has
|
|
been approved. The PR then enters the [merge queue][merge-queue], where @bors
|
|
will run all the tests on every platform we support. If it all works out,
|
|
@bors will merge your code into `master` and close the pull request.
|
|
|
|
[merge-queue]: http://buildbot.rust-lang.org/homu/queue/rust
|
|
|
|
## Writing Documentation
|
|
|
|
Documentation improvements are very welcome. The source of `doc.rust-lang.org`
|
|
is located in `src/doc` in the tree, and standard API documentation is generated
|
|
from the source code itself.
|
|
|
|
Documentation pull requests function in the same as other pull requests, though
|
|
you may see a slightly different form of `r+`:
|
|
|
|
@bors: r+ 38fe8d2 rollup
|
|
|
|
That additional `rollup` tells @bors that this change is eligible for a 'rollup'.
|
|
To save @bors some work, and to get small changes through more quickly, when
|
|
@bors attempts to merge a commit that's rollup-eligible, it will also merge
|
|
the other rollup-eligible patches too, and they'll get tested and merged at
|
|
the same time.
|
|
|
|
## Issue Triage
|
|
|
|
Sometimes, an issue will stay open, even though the bug has been fixed. And
|
|
sometimes, the original bug may go stale because something has changed in the
|
|
meantime.
|
|
|
|
It can be helpful to go through older bug reports and make sure that they are
|
|
still valid. Load up an older issue, double check that it's still true, and
|
|
leave a comment letting us know if it is or is not. The [least recently updated sort][lru] is good for finding issues like this.
|

## Out-of-tree Contributions
|
|
|
|
There are a number of other ways to contribute to Rust that don't deal with
|
|
this repository.
|
|
|
|
Answer questions in [#rust][pound-rust], or on [users.rust-lang.org][users],
|
|
or on [StackOverflow][so].
|
|
|
|
Participate in the [RFC process](https://github.com/rust-lang/rfcs).
|
|
|
|
Find a [requested community library][community-library], build it, and publish
|
|
it to [Crates.io](http://crates.io). Easier said than done, but very, very
|
|
valuable!
