Struct Injector 

pub struct Injector { /* private fields */ }

High-level packet injection handle.

Wraps AfPacketTx. TPACKET_V3 TX uses V1 frame-based semantics.

Examples

let mut tx = netring::Injector::builder()
    .interface("lo")
    .build()
    .unwrap();

if let Some(mut slot) = tx.allocate(64) {
    slot.data_mut()[0..6].copy_from_slice(&[0xff; 6]);
    slot.set_len(64);
    slot.send();
}
tx.flush().unwrap();

Implementations

impl Injector

pub fn builder() -> InjectorBuilder

Start building a new injector.

pub fn allocate(&mut self, len: usize) -> Option<TxSlot<'_>>

Allocate a TX frame. Returns None if the ring is full.

pub fn flush(&mut self) -> Result<usize, Error>

Flush all pending frames to the wire. Returns the count flushed.

pub fn into_inner(self) -> AfPacketTx

Unwrap into the low-level AfPacketTx.

Trait Implementations

impl AsFd for Injector

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl Debug for Injector

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