Research direction

Start with compio-quic/src/endpoint.rs at the panic on line 65, then reproduce the issue using compio-quic/examples/quic-server.rs and the empty-packet client shown in the report. Done means receiving an empty UDP packet no longer panics the QUIC server.

Written by the indexing model from the issue text.

Description

bug good first issue package: quic

A client like this may cause the server to panic:

#[compio_macros::main]
async fn main() {
    let socket = compio_net::UdpSocket::bind("[::1]:0").await.unwrap();
    socket.send_to([], "[::1]:4433").await.unwrap();
}

Running compio-quic/examples/quic-server.rs:

thread 'main' (3777462) panicked at compio-quic/src/endpoint.rs:65:14:
chunk size must be non-zero
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
