Trait retain_mut::RetainMut [−][src]
pub trait RetainMut<T> {
fn retain_mut<F>(&mut self, f: F)
where
F: FnMut(&mut T) -> bool;
}Trait that provides retain_mut method.
Required methods
fn retain_mut<F>(&mut self, f: F) where
F: FnMut(&mut T) -> bool, [src]
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.
