Struct ArrayBuf 

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

A fixed-size array buffer that can be allocated on the stack and used as a backing store for channels.

Implementations

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

pub const fn new() -> Self

Creates a new, empty array buffer with a user-defined - but fixed - capacity.

Trait Implementations

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

fn default() -> Self

Returns the “default value” for a type.

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

fn drop(&mut self)

Executes the destructor for this type.

impl<const N: usize, T> RingBuf for ArrayBuf<N, T>

type Item = T

The type of item stored inside the ring buffer.

fn enqueue(&mut self, item: T) -> Result<(), T>

Places an item into the buffer, returning an Ok result if successful and the item wrapped in an Err result if the buffer is full.

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

Extracts an item from the buffer, returning None if the buffer is empty.

fn clear(&mut self)

Removes all stored elements from the buffer.

fn len(&self) -> usize

Returns the number of elements that are currently stored in the buffer.

fn is_empty(&self) -> bool

Returns whether the buffer is currently empty.
