Type Alias rustc_middle::ty::GenericArgsRef

pub type GenericArgsRef<'tcx> = &'tcx GenericArgs<'tcx>;

Trait Implementations

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

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

impl<'tcx> Key for GenericArgsRef<'tcx>

type CacheSelector = DefaultCacheSelector<&'tcx List<GenericArg<'tcx>>>

fn default_span(&self, _: TyCtxt<'_>) -> Span

In the event that a cycle occurs, if no explicit span has been given for a query with key self, what span should we use?

fn key_as_def_id(&self) -> Option<DefId>

If the key is a DefId or DefId–equivalent, return that DefId. Otherwise, return None.

fn ty_def_id(&self) -> Option<DefId>

impl<'tcx> Relate<'tcx> for GenericArgsRef<'tcx>

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

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for GenericArgsRef<'tcx>

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

where F: TypeFolder<I>,

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.
