Struct ArrayQueue 

pub struct ArrayQueue<T, const N: usize> { /* private fields */ }

A queue backed by a fixed-size array.

Implementations

impl<T, const N: usize> ArrayQueue<T, N>

pub const fn new() -> Self

Creates an empty queue.

pub const fn first(&self) -> Option<&T>

Returns a reference to the first element of the queue, or None if it is empty.

pub const fn first_mut(&mut self) -> Option<&mut T>

Returns a mutable reference to the first element of the queue, or None if it is empty.

pub const fn last(&self) -> Option<&T>

Returns a reference to the last element of the queue, or None if it is empty.

pub const fn last_mut(&mut self) -> Option<&mut T>

Returns a mutable reference to the last element of the queue, or None if it is empty.

pub fn push_front(&mut self, x: T) -> Result<(), CapacityError>

Pushes an element to the front of the queue.

pub fn push_back(&mut self, x: T) -> Result<(), CapacityError>

Pushes an element to the back of the queue.

pub const fn pop_front(&mut self) -> Option<T>

Pops an element from the front of the queue.

pub const fn pop_back(&mut self) -> Option<T>

Pops an element from the back of the queue.

pub const fn len(&self) -> usize

Returns the number of elements in the queue.

pub const fn is_empty(&self) -> bool

Returns true if the queue is empty.

pub const fn is_full(&self) -> bool

Returns true if the queue is full.

Trait Implementations

impl<T: Clone, const N: usize> Clone for ArrayQueue<T, N>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug, const N: usize> Debug for ArrayQueue<T, N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, const N: usize> Default for ArrayQueue<T, N>

fn default() -> Self

Returns the “default value” for a type.

impl<T, const N: usize> Drop for ArrayQueue<T, N>

fn drop(&mut self)

impl<'a, T, const N: usize> IntoIterator for &'a ArrayQueue<T, N>

type Item = &'a T
