Can it support full duplex?

[xutianyi1999]

I don’t know the actual operation of npcap or libpcap
If it is supported, I hope the API can operate like this:

let (rx, tx) = device.open().unwrap();

thread::spawn(move || {
    ......
    tx.sendpacket(...);
});

while let Ok(packet) = rx.next(){
    ......
}

I believe that it does, but not in the way you show it. pcap does not create a separate tx and rx channel (perhaps there is one within libpcap though, but that's out of scope of this crate. Rather, you create a single Capture, you pick up packets with next, and send packets with sendpacket.

I will close this issue to prevent accumulating stale issues, but do not hesitation to reopen if this does not answer your question!

Same problem here.

Rather, you create a single Capture, you pick up packets with next, and send packets with sendpacket.

The problem is the packet can not be sent at anytime. It must wait the next return and send the packet.
