rawsock 0.3.0

Library for receiving and sending raw packets. While most crate wrap just one library, rawsock allows you to use pcap, wpcap, npcap and pf_ring (pfring) using a consistent API for all of them.

/*!
    This example shows automatic choosing of the best underlying library available on your system
    and dynamic dispatch of calls to the right implementation.
    To the user is is unknown if the pcap or wpcap or pfring library is chosen.

    For most applications this is the recommended approach.
