trillium-server-common-v0.7.3

Added

• QuicConfig::bind_with_socket(self, socket, runtime, info) — new non-breaking trait method that
  takes a pre-claimed std::net::UdpSocket instead of a SocketAddr. Default implementation
  delegates back to bind via socket.local_addr(). Adapters should override to consume the
  pre-claimed socket directly.
• ArcedQuicEndpoint::local_addr(&self) -> io::Result<SocketAddr> — the local address the endpoint
  is bound to.
• QuicEndpoint::local_addr(&self) -> io::Result<SocketAddr> — the local address the endpoint is
  bound to. The default implementation returns io::ErrorKind::Unsupported; adapters with a bound
  UDP socket override it to return the actual address.
• bind_reuse_port(addr) -> io::Result<TcpListener> (Unix only, excluding Apple platforms) — bind a
  non-blocking std TcpListener with SO_REUSEPORT + SO_REUSEADDR for kernel connection fan-out
  across a listener group. Gated off on Apple platforms, where SO_REUSEPORT delivers every
  connection to a single listener rather than fanning out.
• Config::listeners(self) -> ListenerConfig — bridge from the single-listener Config into the
  multi-listener ListenerConfig, carrying over global server configuration (HTTP config, shared
  state, swansong, nodelay, max-connections, signals) but no listener binding (bind explicitly on
  the builder). Available before an acceptor/QUIC config is set.
• BoundInfo::listeners() -> &[trillium::Listener] — every listener the server is bound to. The
  builder produces one trillium::Listener per bind_* (TLS-vs-plaintext from each acceptor); the
  single-listener Config path synthesizes its own.
• Each Conn now carries its originating trillium::Listener in state (readable via
  conn.state::<Listener>()), across HTTP/1, HTTP/2, and HTTP/3. The ingress SocketAddr continues
  to be stamped alongside it for addressed listeners, so existing conn.state::<SocketAddr>()
  readers are unaffected; Unix-socket conns now have provenance they previously lacked.
