Implementations§

Source§

impl<St> RlpxProtocolMultiplexer<St>

Source

pub fn new(conn: P2PStream<St>) -> Self

Source

pub fn install_protocol<F, Proto>( &mut self, cap: &Capability, f: F, ) -> Result<(), UnsupportedCapabilityError>
where F: FnOnce(ProtocolConnection) -> Proto, Proto: Stream<Item = BytesMut> + Send + 'static,

Installs a new protocol on top of the raw p2p stream.

This accepts a closure that receives a ProtocolConnection that will yield messages for the given capability.

Source

pub const fn shared_capabilities(&self) -> &SharedCapabilities

Returns the SharedCapabilities of the underlying raw p2p stream

Source

pub fn into_satellite_stream<F, Primary>( self, cap: &Capability, primary: F, ) -> Result<RlpxSatelliteStream<St, Primary>, P2PStreamError>
where F: FnOnce(ProtocolProxy) -> Primary,

Converts this multiplexer into a RlpxSatelliteStream with the given primary protocol.

Source

pub async fn into_satellite_stream_with_handshake<F, Fut, Err, Primary>( self, cap: &Capability, handshake: F, ) -> Result<RlpxSatelliteStream<St, Primary>, Err>
where F: FnOnce(ProtocolProxy) -> Fut, Fut: Future<Output = Result<Primary, Err>>, St: Stream<Item = Result<BytesMut>> + Sink<Bytes, Error = Error> + Unpin, P2PStreamError: Into<Err>,

Converts this multiplexer into a RlpxSatelliteStream with the given primary protocol.

Returns an error if the primary protocol is not supported by the remote or the handshake failed.

Source

pub async fn into_satellite_stream_with_tuple_handshake<F, Fut, Err, Primary, Extra>( self, cap: &Capability, handshake: F, ) -> Result<(RlpxSatelliteStream<St, Primary>, Extra), Err>
where F: FnOnce(ProtocolProxy) -> Fut, Fut: Future<Output = Result<(Primary, Extra), Err>>, St: Stream<Item = Result<BytesMut>> + Sink<Bytes, Error = Error> + Unpin, P2PStreamError: Into<Err>,

Converts this multiplexer into a RlpxSatelliteStream with the given primary protocol.

Returns an error if the primary protocol is not supported by the remote or the handshake failed.

This accepts a closure that does a handshake with the remote peer and returns a tuple of the primary stream and extra data.

Source

pub async fn into_eth_satellite_stream<N: NetworkPrimitives>( self, status: Status, fork_filter: ForkFilter, ) -> Result<(RlpxSatelliteStream<St, EthStream<ProtocolProxy, N>>, Status), EthStreamError>
where St: Stream<Item = Result<BytesMut>> + Sink<Bytes, Error = Error> + Unpin,

Converts this multiplexer into a RlpxSatelliteStream with eth protocol as the given primary protocol.
