List all traits implemented by a type in a scope

Question

For the sake of making debugging easier and such, I would like to know all traits implemented for a type within a certain scope. Can I get rustc to provide me this information? If so, how?

Answer 1

Use rustdoc/cargo doc.

rustdoc creates a section with all trait implementations for a given type. For example with Vec:

If you would like to do this for your own crate, you might find --document-private-items to be useful. See also How to generate documentation for private items.
