I'm excited to learn Rust actually so we might support it soon! It's not trivial to add support new languages since the engine app that runs user-submitted code needs to be able to run arbitrary code in your chosen language and needs a way to communicate with Python (either directly or through JSON passing). So far we've just been adding support for languages we know and use. But indeed there are hundreds of languages out there that would be nice to support in some way. I'm gonna think about how we can add a new "submission mode" where you're given a couple of test cases that you run manually with any language then submit your solution.
