One can't add headers (shortened to hdr) when sending or receiving packets. This prevents QUIC implementations from using this library, as those require header control.

Would it be possible to give the user functions which take headers (e.g. this opcode)?

quinn-rs/quinn#1452 seems to be blocked on this.

Can you use Udpsocket::recvmsg? It's been in master since late Feb. So would have to pull from git.

Right, didn't see that. Thanks!

I noticed you only provide sendmsg_zc. Is there a reason you don't support sendmsg without zero copying?
