rustdoc: handle generics better when matching notable traits This commit makes the `clean::Type::is_same` non-commutative, so that a generic `impl` matches a concrete return, but a generic return does not match a concrete `impl`. It makes slice and vector Write for `u8` not match on every generic return value. 2023-03-09 14:41:13 -06:00
