Struct simrs::Fifo

pub struct Fifo<T> { /* fields omitted */ }

Abstraction over VecDeque that allows to limit the capacity of the queue. This means that push operations can fail. By default, the capacity is equal to usize::MAX, which makes unlimited in practice.

Implementations

impl<T> Fifo<T>

#[must_use]pub fn bounded(capacity: usize) -> Self

Creates a new queue with limited capacity.

Trait Implementations

impl<T> Default for Fifo<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Queue for Fifo<T>

type Item = T

Type of elements held by the queue.

fn push(&mut self, value: T) -> Result<(), PushError>

Add an element to the queue.

fn pop(&mut self) -> Option<T>

Removes the next element and returns it, or None if the Queue is empty.

fn len(&self) -> usize

Returns the number of elements in the queue.

fn is_empty(&self) -> bool

Returns true if there are no elements in the queue.
