Struct rustc::ty::ProjectionTy [−] [src]

pub struct ProjectionTy<'tcx> {
    pub trait_ref: TraitRef<'tcx>,
    pub item_name: Name,
}
Unstable (rustc_private)

Represents the projection of an associated type. In explicit UFCS form this would be written <T as Trait<..>>::N.

Fields

trait_ref: TraitRef<'tcx>
Unstable (rustc_private)

The trait reference T as Trait<..>.

item_name: Name
Unstable (rustc_private)

The name N of the associated type.
