Required Associated Types

type Item

Item type.

Required Methods

fn empty() -> Self

Creat an empty queue.

fn len(&self) -> usize

Get the nubmer of items in queue.

fn deque(&mut self) -> Option<Self::Item>

Deque an item.

fn enque(&mut self, item: Self::Item)

Enque a new item.

fn get_latest(&self, n: usize) -> Option<&Self::Item>

Get the nth latest item.

The index is starting from 0.

Provided Methods

fn is_empty(&self) -> bool

Is empty.

fn is_reach(&self) -> bool

Tumbling full.

fn enque_and_deque_overflow(&mut self, item: Self::Item) -> Option<Self::Item>

Push a new item and return the oldest item if full.
