Struct libp2p_request_response::handler::Handler

pub struct Handler<TCodec>where
    TCodec: Codec,{ /* private fields */ }

A connection handler for a request response Behaviour protocol.

Trait Implementations

impl<TCodec> ConnectionHandler for Handler<TCodec>where TCodec: Codec + Send + Clone + 'static,

type InEvent = RequestProtocol<TCodec>

Custom event that can be received from the outside.

type OutEvent = Event<TCodec>

Custom event that can be produced by the handler and that will be returned to the outside.

type Error = ConnectionHandlerUpgrErr<Error>

The type of errors returned by ConnectionHandler::poll.

type InboundProtocol = ResponseProtocol<TCodec>

The inbound upgrade for the protocol(s) used by the handler.

type OutboundProtocol = RequestProtocol<TCodec>

The outbound upgrade for the protocol(s) used by the handler.

type OutboundOpenInfo = RequestId

The type of additional information passed to an OutboundSubstreamRequest.

type InboundOpenInfo = RequestId

The type of additional information returned from listen_protocol.

fn listen_protocol( &self ) -> SubstreamProtocol<Self::InboundProtocol, Self::InboundOpenInfo>

The InboundUpgrade to apply on inbound substreams to negotiate the desired protocols.

fn on_behaviour_event(&mut self, request: Self::InEvent)

Informs the handler about an event from the NetworkBehaviour.

fn connection_keep_alive(&self) -> KeepAlive

Returns until when the connection should be kept alive.

fn poll( &mut self, cx: &mut Context<'_> ) -> Poll<ConnectionHandlerEvent<RequestProtocol<TCodec>, RequestId, Self::OutEvent, Self::Error>>

Should behave like Stream::poll().

fn on_connection_event( &mut self, event: ConnectionEvent<'_, Self::InboundProtocol, Self::OutboundProtocol, Self::InboundOpenInfo, Self::OutboundOpenInfo> )

fn map_in_event<TNewIn, TMap>(self, map: TMap) -> MapInEvent<Self, TNewIn, TMap>where Self: Sized, TMap: Fn(&TNewIn) -> Option<&Self::InEvent>,

Adds a closure that turns the input event into something else.

fn map_out_event<TMap, TNewOut>(self, map: TMap) -> MapOutEvent<Self, TMap>where Self: Sized, TMap: FnMut(Self::OutEvent) -> TNewOut,

Adds a closure that turns the output event into something else.

fn select<TProto2>( self, other: TProto2 ) -> ConnectionHandlerSelect<Self, TProto2>where Self: Sized,

Creates a new ConnectionHandler that selects either this handler or other by delegating methods calls appropriately.
