Libp2pQuicTransport class

A libp2p transport backed by QUIC.

Libp2pQuicTransport wraps a QuicEndpoint and exposes libp2p-style listen and dial APIs. It parses Multiaddr values to extract IP addresses and UDP ports, binds the endpoint, and bridges raw QuicConnection objects into Libp2pQuicConnection wrappers.

Per the libp2p QUIC specification, the security handshake (Noise or TLS 1.3 with libp2p extension) runs inside the QUIC crypto frame stream. This transport layer handles addressing and connection establishment; the actual security handshake is performed by the libp2p security upgrade layer above it.

Example

final transport = Libp2pQuicTransport();

// Listen on a multiaddr.
final incoming = await transport.listen(
  Multiaddr.parse('/ip4/127.0.0.1/udp/0/quic-v1'),
);
incoming.listen((conn) {
  print('Accepted connection: ${conn.quicConnection}');
  conn.close();
});

// Dial a remote peer.
final conn = await transport.dial(
  Multiaddr.parse('/ip4/192.168.1.10/udp/4001/quic-v1'),
);
conn.send(Uint8List.fromList([1, 2, 3]));
await transport.close();
