There is no problem really using an index here though and for better design use interior mutability (UnsafeCell) which limits the spread of unsafe to a function on Player.

UnsafeCell is not copy or clone and eq needs to be implemented comparing addresses absent an id (but thats just and example anyway i guess, adding a player id would make sense i guess)

Assembly in this version looks not too bad at first glance either.
