QuicConnection The central API. A sans-I/O state machine that processes inbound datagrams and produces outbound datagrams and events. from zoomies.core import QuicConnection, QuicConfiguration config = QuicConfiguration(certificate=cert, private_key=key) conn = QuicConnection(config) Methods datagram_received Feed a UDP datagram into the connection. Returns a list of events. events: list[QuicEvent] = conn.datagram_received(data: bytes, addr: tuple) send_datagrams Get outbound datagrams that the connection wants to send. datagrams: list[bytes] = conn.send_datagrams() get_next_stream_id Allocate the next available stream ID. stream_id: int = conn.get_next_stream_id() send_stream_data Queue data for transmission on a stream. conn.send_stream_data(stream_id: int, data: bytes, end_stream: bool = False) get_timer Get the next timer deadline (absolute time). Returns None if no timer is pending. timeout: float | None = conn.get_timer() handle_timer Process a timer expiry. Returns events (e.g., retransmission, PTO probe). events: list[QuicEvent] = conn.handle_timer() close Initiate connection close with an optional error code. conn.close(error_code: int = 0, reason_phrase: str = "")
