That's an internal pointer, and internal pointers are not allowed 
in structs precisely because of the issues you're running into: 
the pointer will be invalid after a move.

You may be able to get it kind of working, but I'd recommend 
looking for another solution to your problem. This is one of 
those things that will come back to bite you later.
