Enum PointerMeta 

pub enum PointerMeta<Provenance>
where
    Provenance: Obj,
{
    ElementCount(Int),
    VTablePointer(ThinPointer<Provenance>),
}

The runtime metadata that can be stored in a wide pointer.

Variants

ElementCount(Int)

The metadata counts the number of elements in the slice.

VTablePointer(ThinPointer<Provenance>)

The metadata points to a vtable referred at this location. This must point to a valid vtable and it is a spec bug if it doesn’t.
