Struct rustc_middle::ty::sty::ExistentialProjection[][src]

pub struct ExistentialProjection<'tcx> {
    pub item_def_id: DefId,
    pub substs: SubstsRef<'tcx>,
    pub ty: Ty<'tcx>,
}

A ProjectionPredicate for an ExistentialTraitRef.

Fields

item_def_id: DefIdsubsts: SubstsRef<'tcx>ty: Ty<'tcx>

Implementations

impl<'tcx> ExistentialProjection<'tcx>[src]

pub fn trait_ref(&self, tcx: TyCtxt<'tcx>) -> ExistentialTraitRef<'tcx>[src]

Extracts the underlying existential trait reference from this projection. For example, if this is a projection of exists T. <T as Iterator>::Item == X, then this function would return a exists T. T: Iterator existential trait reference.
