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.
