## Filing a pull request

Check out [Servo's Github workflow](https://github.com/servo/servo/wiki/Github-workflow) for an overview on creating a pull request.

Don't worry about requesting code review, as there is nothing formally setup for this repository. I try and review each pull request as soon as I can.

There is continuous integration setup for `cbindgen` using [travis](https://travis-ci.org/). It automatically runs `cargo test` which runs `cbindgen` against a series of rust files from `tests/rust/` and checks that the output compiles using `gcc` or `g++`.

Please run `cargo test` before filing a pull request to be sure that all tests pass. This will also update the test expectations.

Rustfmt is also enforced by travis. To format your code install `rustfmt-preview` using `rustup component add rustfmt-preview` and then `cargo fmt`. Travis runs with rust nightly, so use `rustup run nightly -- cargo fmt` to guarantee consistent results.

Writing new tests with your pull requests is also appreciated.
