Struct rustc::ty::ProjectionTy
[−]
[src]
pub struct ProjectionTy<'tcx> { pub trait_ref: TraitRef<'tcx>, pub item_name: Name, }
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>
rustc_private
)The trait reference T as Trait<..>
.
item_name: Name
rustc_private
)The name N
of the associated type.
