pub(super) fn vtable_allocation_provider<'tcx>(
tcx: TyCtxt<'tcx>,
key: (Ty<'tcx>, Option<PolyExistentialTraitRef<'tcx>>),
) -> AllocId
Expand description
Retrieves an allocation that represents the contents of a vtable. Since this is a query, allocations are cached and not duplicated.
This is an “internal” AllocId
that should never be used as a value in the interpreted program.
The interpreter should use AllocId
that refer to a GlobalAlloc::VTable
instead.
(This is similar to statics, which also have a similar “internal” AllocId
storing their
initial contents.)
