Expand description
Trait to enable sending $packet
packets.
Required Methods
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.
