A tool for formatting Rust code according to style guidelines. You can use rustfmt in Travis CI builds. We provide a minimal Travis CI configuration (see here) and verify its status using another repository. You can run rustfmt with Rust 1.24 and above. Rustfmt tries to work on as much Rust code as possible. Sometimes, the code doesn't even need to compile! In general, we are looking to limit areas of instability; in particular, post-1.0, the formatting of most code should not change as Rustfmt...
