Enum rustc_ast::ast::AssocItemConstraintKind

pub enum AssocItemConstraintKind {
    Equality {
        term: Term,
    },
    Bound {
        bounds: GenericBounds,
    },
}

The kind of associated item constraint.

Variants

Equality

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.

Fields

term: Term

Bound

A bound on an associated type (e.g., AssocTy: Bound in Trait<AssocTy: Bound>).

Fields

bounds: GenericBounds
