Performs the actual query with the canonicalized key -- the real work happens here. This method is not given an infcx because it shouldn't need one -- and if it had access to one, it might do things like invoke sub_regions, which would be bad, because it would create subregion relationships that are not captured in the return value.

Casts a lifted query result (which is in the gcx lifetime) into the tcx lifetime. This is always just an identity cast, but the generic code doesn't realize it -- put another way, in the generic code, we have a Lifted<'gcx, Self::QueryResult> and we want to convert that to a Self::QueryResult. This is not a priori valid, so we can't do it -- but in practice, it is always a no-op (e.g., the lifted form of a type, Ty<'gcx>, is a subtype of Ty<'tcx>). So we have to push the operation into the impls that know more specifically what QueryResult is. This operation would (maybe) be nicer with something like HKTs or GATs, since then we could make QueryResult parametric and 'gcx and 'tcx etc. Read more
