Struct ProjectionPredicate 

pub struct ProjectionPredicate<'tcx> {
    pub trait_proof: TraitProof<'tcx>,
    pub assoc_item: AssocItem<'tcx>,
    pub ty: Ty<'tcx>,
}

Expresses a constraints over an associated type.

For instance:

fn f<T : Foo<S = String>>(...)
             ^^^^^^^^^^

(provided the trait Foo has an associated type S).

Fields

assoc_item: AssocItem<'tcx>

The Type in Ty: Trait<..., Type = U>.

ty: Ty<'tcx>

The type U in Ty: Trait<..., Type = U>.
