A ring buffer used to do bulk pops from a RxRing or pushes to a TxRing

This is allocated on the heap, but will not grow, and is intended to be allocated once before entering an I/O loop

Implementations

impl HeapSlab

pub fn with_capacity(capacity: usize) -> Self

Allocates a new Self with the maximum specified capacity

pub fn len(&self) -> usize

The number of packets in the slab

pub fn is_empty(&self) -> bool

True if the slab is empty

pub fn available(&self) -> usize

The number of packets that can be pushed to the slab

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

Pops the front packet if any

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

Pops the back packet if any

pub fn push_front(&mut self, item: Packet) -> Option<Packet>

Pushes a packet to the front, returning Some if the slab is at capacity

pub fn push_back(&mut self, item: Packet) -> Option<Packet>

Pushes a packet to the back, returning Some if the slab is at capacity
