Trait Implementations

impl<'tcx> EraseType for TraitRef<'tcx>

type Result = [u8; 16]

impl<'tcx> Key for TraitRef<'tcx>

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

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

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 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.
