Trait Implementations

impl<T> RingBuf for HeapRingBuf<T>

type Item = T

The type of stored items inside the Ring Buffer

fn new() -> Self

Creates a new instance of the Ring Buffer

fn with_capacity(cap: usize) -> Self

Creates a new instance of the Ring Buffer with the given capacity. RingBuf implementations are allowed to ignore the capacity hint and utilize their default capacity.

fn capacity(&self) -> usize

The capacity of the buffer

fn len(&self) -> usize

The amount of stored items in the buffer

fn can_push(&self) -> bool

Returns true if there is enough space in the buffer to store another item.

fn push(&mut self, value: Self::Item)

Stores the item at the end of the buffer. Panics if there is not enough free space.

fn pop(&mut self) -> Self::Item

Returns the oldest item inside the buffer. Panics if there is no available item.

fn is_empty(&self) -> bool

Returns true if no item is stored inside the buffer.
