Trait TryPush 

pub trait TryPush<T> {
    // Required methods
    fn try_push(&mut self, elem: T) -> Element<T>;
    fn try_push_front(&mut self, elem: T) -> Element<T>;
}

Required Methods

fn try_push(&mut self, elem: T) -> Element<T>

Attempts to push an element to the collection. If that action would re-allocate or require shifting elements then the elem is returned in Element::NotAdded(). Otherwise, the return value is Element::Added.

fn try_push_front(&mut self, elem: T) -> Element<T>

Attempts to push an element front to the collection. If that action would re-allocate or require shifting elements then the elem is returned in Element::NotAdded(). Otherwise, the return value is Element::Added.
