Struct TxRing

Source 
pub struct TxRing { /* private fields */ }
Expand description

The ring used to enqueue packets for the kernel to send

Implementations§

Source§

impl TxRing

Source

pub unsafe fn send(&mut self, packets: &mut HeapSlab) -> usize

Enqueues packets to be sent by the kernel

§Safety

The crate::Umem that owns the packets being sent must outlive the AF_XDP socket

§Returns

The number of packets that were actually enqueued. This number can be lower than the requested num_packets if the ring doesn’t have sufficient capacity
