Trait Implementations§


impl<'tcx> Key for PolyTraitRef<'tcx>


type Cache<V> = DefaultCache<Binder<TyCtxt<'tcx>, TraitRef<TyCtxt<'tcx>>>, V>


fn default_span(&self, tcx: 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>
