E.g. they have a different `size_hint` implementation. The `filter_map` might be faster … WebbThe map iterator implements DoubleEndedIterator, meaning that you can also map backwards: let v: Vec = [1, 2, 3].into_iter ().map ( x x + 1).rev ().collect (); assert_eq!(v, [4, 3, 2]); Run But if your closure has state, iterating backwards may act in a way you do not expect. Let’s go through an example. First, in the forward direction: geass usb
