Place(PlaceRef<'tcx, V>)
UnsizedPlace(PlaceRef<'tcx, V>)
UnsizedPlace(p): p itself is a thin pointer (indirect place).
*p is the fat pointer that references the actual unsized place.
Every time it is initialized, we have to reallocate the place
and update the fat pointer. That’s the reason why it is indirect.

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.
