Struct RequestResponseFactoryBehaviour

pub struct RequestResponseFactoryBehaviour { /* private fields */ }

Implementation of NetworkBehaviour that provides support for multiple request-response protocols.

Implementations

impl RequestResponseFactoryBehaviour

pub fn new( list: impl IntoIterator<Item = Box<dyn RequestHandler>>, ) -> Result<Self, RegisterError>

Creates a new behaviour. Must be passed a list of supported protocols. Returns an error if the same protocol is passed twice.

pub fn send_request( &mut self, target: &PeerId, protocol_name: &str, request: Vec<u8>, pending_response: Sender<Result<Vec<u8>, RequestFailure>>, connect: IfDisconnected, addresses: Vec<Multiaddr>, )

Initiates sending a request.

If there is no established connection to the target peer, the behavior is determined by the choice of connect.

An error is returned if the protocol doesn’t match one that has been registered.

Trait Implementations

impl NetworkBehaviour for RequestResponseFactoryBehaviour

fn on_swarm_event(&mut self, event: FromSwarm<'_>)

Informs the behaviour about an event from the Swarm.

type ConnectionHandler = MultiHandler<String, <Behaviour<GenericCodec> as NetworkBehaviour>::ConnectionHandler>

Handler for all the protocols the network behaviour supports.

type ToSwarm = Event

Event generated by the NetworkBehaviour and that the swarm will report back.

fn handle_established_inbound_connection( &mut self, connection_id: ConnectionId, peer: PeerId, local_addr: &Multiaddr, remote_addr: &Multiaddr, ) -> Result<Self::ConnectionHandler, ConnectionDenied>

Callback that is invoked for every established inbound connection.

fn handle_established_outbound_connection( &mut self, connection_id: ConnectionId, peer: PeerId, addr: &Multiaddr, role_override: Endpoint, port_use: PortUse, ) -> Result<Self::ConnectionHandler, ConnectionDenied>

Callback that is invoked for every established outbound connection.

fn on_connection_handler_event( &mut self, peer_id: PeerId, connection: ConnectionId, event: THandlerOutEvent<Self>, )

Informs the behaviour about an event generated by the [ConnectionHandler] dedicated to the peer identified by peer_id. for the behaviour.

fn poll( &mut self, cx: &mut Context<'_>, ) -> Poll<ToSwarm<Self::ToSwarm, THandlerInEvent<Self>>>

Polls for things that swarm should do.

fn handle_pending_inbound_connection( &mut self, _connection_id: ConnectionId, _local_addr: &Multiaddr, _remote_addr: &Multiaddr, ) -> Result<(), ConnectionDenied>

Callback that is invoked for every new inbound connection.

fn handle_pending_outbound_connection( &mut self, _connection_id: ConnectionId, _maybe_peer: Option<PeerId>, _addresses: &[Multiaddr], _effective_role: Endpoint, ) -> Result<Vec<Multiaddr>, ConnectionDenied>

Callback that is invoked for every outbound connection attempt.
