Implementations

impl<T: Clone + Default> Queue<T>

pub fn new(length: usize) -> Self

Create an empty queue of fixed size

use algorithms_rs::Queue;

let empty_queue = Queue::<i32>::new(1);

assert_eq!(empty_queue.is_empty(), true);

pub fn is_empty(&self) -> bool

Determine if queue is empty

use algorithms_rs::Queue;

let empty_queue = Queue::<i32>::new(1);

assert_eq!(empty_queue.is_empty(), true);

pub fn en_queue(&mut self, element: T) -> Result<()>

Enter the queue from the end of the queue

use algorithms_rs::Queue;

let mut queue = Queue::<i32>::new(3);

queue.en_queue(1);
queue.en_queue(2);

assert_eq!(queue.is_empty(), false);

pub fn de_queue(&mut self) -> Result<T>

From the head of the queue Out of the queue

use algorithms_rs::Queue;

let mut queue = Queue::<i32>::new(3);

queue.en_queue(1);
queue.en_queue(2);

queue.de_queue();
queue.de_queue();

assert_eq!(queue.is_empty(), true);
