Whoa, I have been working with Rust for a little over a year, and had no idea about the [-] button. I would echo the suggestions to make that button much more visible. Or perhaps even have the top-level description expanded by default but method/trait descriptions hidden. I can't think of a case where you'd simultaneously want to see every method description.
