If you ever find yourself stuck for too long, drop a code snippet into https://play.rust-lang.org/ and share a link to the code in IRC channel at #rust or #rust-beginners (irc.mozilla.org). Very friendly community.
I work at GitHub and I’ve been telling people that for the future of open source we really ought to be looking at the Rust community, both the amount of automation they have and also their general communication style.
