§

An equality constraint for an associated item (e.g., AssocTy = Ty in Trait<AssocTy = Ty>).

Also known as an associated item binding (we bind an associated item to a term).

Furthermore, associated type equality constraints can also be referred to as associated type bindings. Similarly with associated const equality constraints and associated const bindings.
