cargo doc --document-private-items This is going to be excellent. I often find in Rust, more than other languages, that the documentation really helps fill a mental gap around the types that you expect a type to implement, vs. what it actually implements. The compiler always catches this, but the docs are also a great way of discovering this. It's going to be a huge help when working on internal interfaces in a library. cargo doc is such an excellent tool, and while the UI took a minute to learn when I first used it, it's really an amazingly helpful tool, and feels more integrated than similar tools in other languages.
