Enum rustc_ast::ast::AssocItemConstraintKind
source · pub enum AssocItemConstraintKind {
Equality {
term: Term,
},
Bound {
bounds: GenericBounds,
},
}
Expand description
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.
Bound
A bound on an associated type (e.g., AssocTy: Bound
in Trait<AssocTy: Bound>
).
Fields
bounds: GenericBounds
