Ask HN/Lazyweb: Favorite rust projects/canonical examples to learn from

I'm starting to become more interested in rust and I believe that the best way to learn a thing is to study good applications of it. As I don't know much at all about the rust ecosystem, I am not qualified to determine what is good, and I'm lazy. So... what's good? What are some good examples of sufficiently complicated rust applications that either a) do a very good job of subscribing to rust dogma or b) do a very good job of hacking around the darker corners to achieve a goal where a canonical example would have been unsuitable?
