BridgeIo

rama::io

Struct BridgeIo 

pub struct BridgeIo<Io1, Io2>(pub Io1, pub Io2);
Available on crate feature std only.
Expand description

A bidirectional bridge between two Io objects.

Often this is for Client-Server communication, but in a P2P like topology it can also be equal nodes.

ExtensionsRef and ExtensionsRef is implemented in function of Io1 as it is assumed that in flows where BridgeIo is used that we keep moving from “left” (Io1) to “right” (Io2) until we start to actually relay bytes, handshakes or any kind of data.

If you ever use Io2’s extensions you can do so explicitly.

§

type Socket = Ingress

The socket an inspection reads from.
§

type Mapped<Peeked: DatagramSocket> = BridgeIo<Peeked, Egress>

This input with its peeked socket replaced, usually by a PrefixedDatagramSocket.
§

fn peek_socket_mut( &mut self, ) -> &mut <BridgeIo<Ingress, Egress> as DatagramPeekInput>::Socket

The socket an inspection reads from.
§

fn map_peek_socket<Peeked, F>( self, map: F, ) -> <BridgeIo<Ingress, Egress> as DatagramPeekInput>::Mapped<Peeked>
where Peeked: DatagramSocket, F: FnOnce(<BridgeIo<Ingress, Egress> as DatagramPeekInput>::Socket) -> Peeked,

Rebuild this input around map’s result for its peeked socket.
§

where Io1: ExtensionsRef,

§

fn extensions(&self) -> &Extensions

§

impl<Ingress, Egress> PeekIoProvider for BridgeIo<Ingress, Egress>
where Ingress: Io, Egress: Io,

§

type PeekIo = Ingress

§

type Mapped<PeekedIngress: Io> = BridgeIo<PeekedIngress, Egress>

§

fn peek_io_mut( &mut self, ) -> &mut <BridgeIo<Ingress, Egress> as PeekIoProvider>::PeekIo

where A: DatagramSocket, B: DatagramSocket,

Forward between two connected sockets, as Peer::connected makes them: a DatagramToProxyBridge association, for example.

§

type Output = ()

The type of the output returned by the service.
§

type Error = DatagramForwardError

The type of error returned by the service.

impl Service<BridgeIo<Connection, Connection>> for QuicRelay

§

fn serve( &self, _: BridgeIo<Connection, Connection>, ) -> impl Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send

Relay dedicated, established connections until either connection ends.

ingress is a server connection and egress a client connection. Both hops must negotiate the same nonempty ALPN. Do not consume their streams or datagrams concurrently elsewhere. Configure receive datagram advertisements to match this policy before establishing either hop. Neither hop may have enabled early-data keys: this generic relay does not decide application replay safety. Configure TLS early data off on both hops.

Dropping this future closes both connections, including streams waiting for remote credit. Connection-level transport errors are returned locally and mapped to failure_code on the other hop; they are not fabricated as transport errors belonging to that independent connection.
