impl<'tcx, T: Clone> Key for Canonical<'tcx, T>

Canonical query goals correspond to abstract trait operations that are not tied to any crate in particular.

type Cache<V> = DefaultCache<Canonical<TyCtxt<'tcx>, T>, 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>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
