Is it possible to make a type only movable and not copyable?
...ess you explicitly implement it for your type:
struct Triplet {
one: i32,
two: i32,

}
impl Copy for Triplet {} // add this for copy, leave it out for move

(Using ContainsKey and then the the indexer makes it look the key up twice, which is pretty pointless.)

The former could result in a tiny allocation and subsequent buffer overflows, if ...
