ekuber, (edited ) Meet Red Pen, a rudimentary #Rust linter: https://github.com/estebank/redpen
I cleaned things up to the point where you can actually use this, but it is v0.1 and I mean it. It most likely won't work when you first try it (linux only for now), but I'm really happy with the first useful lint it has: assert that a function cannot call panic.PRs very welcome.
