Struct RxRing 

pub struct RxRing { /* private fields */ }

Circular descriptor ring for AF_XDP RX packets.

Implementations

impl RxRing

pub fn new(capacity: u32) -> Self

Creates a new RX ring with capacity descriptors. capacity must be a power of two.

pub fn capacity(&self) -> u32

Maximum number of descriptors the ring can hold.

pub fn len(&self) -> usize

Number of descriptors currently queued in the ring.

pub fn is_empty(&self) -> bool

Returns true if the ring has no queued descriptors.

pub fn is_full(&self) -> bool

Returns true if the ring is at maximum capacity.

pub fn produce(&mut self, desc: XskDesc) -> bool

Enqueues a descriptor into the RX ring. Returns false if full.

pub fn produce_batch(&mut self, descs: &[XskDesc]) -> usize

Enqueues a batch of descriptors into the RX ring. Returns count enqueued.

pub fn consume(&mut self) -> Option<XskDesc>

Dequeues a descriptor from the RX ring.

pub fn consume_batch(&mut self, out: &mut [XskDesc]) -> usize

Dequeues up to out.len() descriptors into out. Returns count dequeued.

Trait Implementations

impl Clone for RxRing

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for RxRing

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