    },
    Bound {
        bounds: GenericBounds,
    },
}

The kinds of an AssocConstraint.

Variants

Equality

Fields

term: Term

E.g., A = Bar, A = 3 in Foo<A = Bar> where A is an associated type.

Bound

Fields

bounds: GenericBounds

E.g. A: TraitA + TraitB in Foo<A: TraitA + TraitB>.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
