pub struct TaggedPtr<P, T, const COMPARE_PACKED: bool>where
    P: Pointer,
    T: Tag,{
    raw: CopyTaggedPtr<P, T, COMPARE_PACKED>,
}

Expand description

A TaggedPtr implementing Drop.

If COMPARE_PACKED is true, then the pointers will be compared and hashed without unpacking. Otherwise we don’t implement PartialEq/Eq/Hash; if you want that, wrap the TaggedPtr.
