Type Definition rustc_middle::ty::subst::SubstsRef

pub type SubstsRef<'tcx> = &'tcx InternalSubsts<'tcx>;

Trait Implementations

impl<'tcx, D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<D> for SubstsRef<'tcx>

fn decode(decoder: &mut D) -> Self

impl<'tcx> Relate<'tcx> for SubstsRef<'tcx>

fn relate<R: TypeRelation<'tcx>>(
    relation: &mut R,
    a: SubstsRef<'tcx>,
    b: SubstsRef<'tcx>
) -> RelateResult<'tcx, SubstsRef<'tcx>>

impl<'tcx> TypeFoldable<'tcx> for SubstsRef<'tcx>

fn try_fold_with<F: FallibleTypeFolder<'tcx>>(
    self,
    folder: &mut F
) -> Result<Self, F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F: TypeFolder<'tcx>>(self, folder: &mut F) -> Self

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
