fn split_coroutine_args(self) -> CoroutineArgsParts<TyCtxt<'tcx>>

fn as_closure(self) -> ClosureArgs<I>

fn as_coroutine_closure(self) -> CoroutineClosureArgs<I>

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

type Cache<V> = DefaultCache<&'tcx RawList<(), GenericArg<'tcx>>, V>

The type of in-memory cache to use for queries with this key type.

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 def_id_for_ty_in_cycle(&self) -> Option<DefId>

Used to detect when ADT def ids are used as keys in a cycle for better error reporting.

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

fn relate<R: TypeRelation<TyCtxt<'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: TypeFolder<TyCtxt<'tcx>>>(self, folder: &mut F) -> Self

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

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.
