Struct h3_quinn::Endpoint

pub struct Endpoint { /* private fields */ }

A QUIC endpoint.

An endpoint corresponds to a single UDP socket, may host many connections, and may act as both client and server for different connections.

May be cloned to obtain another handle to the same endpoint.

Implementations

impl Endpoint

pub fn new( config: EndpointConfig, server_config: Option<ServerConfig>, socket: UdpSocket, runtime: Arc<dyn Runtime + 'static> ) -> Result<Endpoint, Error>

Construct an endpoint with arbitrary configuration and socket

pub fn new_with_abstract_socket( config: EndpointConfig, server_config: Option<ServerConfig>, socket: impl AsyncUdpSocket, runtime: Arc<dyn Runtime + 'static> ) -> Result<Endpoint, Error>

Construct an endpoint with arbitrary configuration and pre-constructed abstract socket

Useful when socket has additional state (e.g. sidechannels) attached for which shared ownership is needed.

pub fn accept(&self) -> Accept<'_>

Get the next incoming connection attempt from a client

Yields Connecting futures that must be awaited to obtain the final Connection, or None if the endpoint is closed.

pub fn set_default_client_config(&mut self, config: ClientConfig)

Set the client configuration used by connect

pub fn connect( &self, addr: SocketAddr, server_name: &str ) -> Result<Connecting, ConnectError>

Connect to a remote endpoint

server_name must be covered by the certificate presented by the server. This prevents a connection from being intercepted by an attacker with a valid certificate for some other server.

May fail immediately due to configuration errors, or in the future if the connection could not be established.

pub fn connect_with( &self, config: ClientConfig, addr: SocketAddr, server_name: &str ) -> Result<Connecting, ConnectError>

Connect to a remote endpoint using a custom configuration.

See connect() for details.

pub fn rebind(&self, socket: UdpSocket) -> Result<(), Error>

Switch to a new UDP socket

Allows the endpoint’s address to be updated live, affecting all active connections. Incoming connections and connections to servers unreachable from the new address will be lost.

On error, the old UDP socket is retained.

pub fn set_server_config(&self, server_config: Option<ServerConfig>)

Replace the server configuration, affecting new incoming connections only

Useful for e.g. refreshing TLS certificates without disrupting existing connections.

pub fn local_addr(&self) -> Result<SocketAddr, Error>

Get the local SocketAddr the underlying socket is bound to

pub fn close(&self, error_code: VarInt, reason: &[u8])

Close all of this endpoint’s connections immediately and cease accepting new connections.

See Connection::close() for details.

pub async fn wait_idle(&self) -> impl Future<Output = ()>

Wait for all connections on the endpoint to be cleanly shut down

Waiting for this condition before exiting ensures that a good-faith effort is made to notify peers of recent connection closes, whereas exiting immediately could force them to wait out the idle timeout period.

Does not proactively close existing connections or cause incoming connections to be rejected. Consider calling close() if that is desired.

Trait Implementations

impl Clone for Endpoint

fn clone(&self) -> Endpoint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Endpoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
