Rust open-source contributions stream

This time we're trying something new! We're going to go through a few open-source Rust projects and see if we can contribute something to them. In about 90 minutes per crate, we'll go through the crate's organization and API, look for things that look out-of-place or can be improved, and then try to make and submit a PR that fixes it!
