Pointer is an opaque typed pointer and is guaranteed to be comparable.

type Pointer struct {
	p unsafe.Pointer
	t reflect.Type
}

PointerOf returns a Pointer from v, which must be a reflect.Ptr, reflect.Slice, or reflect.Map.

The proper representation of a pointer is unsafe.Pointer, which is necessary if the GC ever uses a moving collector.

	return Pointer{unsafe.Pointer(v.Pointer()), v.Type()}
}

IsNil reports whether the pointer is nil.

func (p Pointer) IsNil() bool {
	return p.p == nil
}

Uintptr returns the pointer as a uintptr.

func (p Pointer) Uintptr() uintptr {
	return uintptr(p.p)
