Huh? They serve two different purposes. `move_iter` returns an iterator that consumes values (i.e., ownership transfers) while `iter` consumes borrowed references to values (i.e., no ownership transfer).
The only place in the code, that I can spot, where `move_iter` is even available is on line 46. But I don't see any compelling reason to use move_iter there (plus, `validation_sample.len()` in the final println would have to be moved up and let bound before the call to move_iter).
