Trait that provides retain_mut method.

Required methods

fn retain_mut<F>(&mut self, f: F) where
    F: FnMut(&mut T) -> bool, [−]

Retains only the elements specified by the predicate.

In other words, remove all elements e such that f(&e) returns false. This method operates in place, visiting each element exactly once in the original order, and preserves the order of the retained elements.
