Struct rustc::ty::TraitTy [−] [src]

pub struct TraitTy<'tcx> {
    pub principal: PolyTraitRef<'tcx>,
    pub bounds: ExistentialBounds<'tcx>,
}
Unstable (rustc_private)

Fields

principal: PolyTraitRef<'tcx>
Unstable (rustc_private)
bounds: ExistentialBounds<'tcx>
Unstable (rustc_private)

Methods

impl<'a, 'gcx, 'tcx> TraitTy<'tcx>
[src]

fn principal_def_id(&self) -> DefId

fn principal_trait_ref_with_self_ty(&self, tcx: TyCtxt<'a, 'gcx, 'tcx>, self_ty: Ty<'tcx>) -> PolyTraitRef<'tcx>

Unstable (rustc_private)

Object types don't have a self-type specified. Therefore, when we convert the principal trait-ref into a normal trait-ref, you must give some self-type. A common choice is mk_err() or some skolemized type.

fn projection_bounds_with_self_ty(&self, tcx: TyCtxt<'a, 'gcx, 'tcx>, self_ty: Ty<'tcx>) -> Vec<PolyProjectionPredicate<'tcx>>

fn is_global(&self) -> bool

Indicates whether this value references only 'global' types/lifetimes that are the same regardless of what fn we are in. This is used for caching. Errs on the side of returning false. Read more
