TraitConstraint

std::meta::trait_constraint contains methods on the built-in TraitConstraint type which represents a trait constraint that can be used to search for a trait implementation. This is similar syntactically to just the trait itself, but can also contain generic arguments. E.g. Eq, Default, BuildHasher<Poseidon2Hasher>.

This type currently has no public methods but it can be used alongside Type in implements or get_trait_impl.
