Trait pnet_datalink::DataLinkSender

pub trait DataLinkSender: Send {
    fn build_and_send(
        &mut self, 
        num_packets: usize, 
        packet_size: usize, 
        func: &mut dyn FnMut(&mut [u8])
    ) -> Option<Result<()>>;
    fn send_to(
        &mut self, 
        packet: &[u8], 
        dst: Option<NetworkInterface>
    ) -> Option<Result<()>>;
}

Trait to enable sending $packet packets.

Required methods

fn build_and_send(
    &mut self,
    num_packets: usize,
    packet_size: usize,
    func: &mut dyn FnMut(&mut [u8])
) -> Option<Result<()>>

Create and send a number of packets.

This will call func num_packets times. The function will be provided with a mutable packet to manipulate, which will then be sent. This allows packets to be built in-place, avoiding the copy required for send. If there is not sufficient capacity in the buffer, None will be returned.

fn send_to(
    &mut self,
    packet: &[u8],
    dst: Option<NetworkInterface>
) -> Option<Result<()>>

Send a packet.

This may require an additional copy compared to build_and_send, depending on the operating system being used. The second parameter is currently ignored, however None should be passed.
