Trait Implementations§
source§impl<TCodec> ConnectionHandler for Handler<TCodec>
impl<TCodec> ConnectionHandler for Handler<TCodec>
§type InEvent = RequestProtocol<TCodec>
type InEvent = RequestProtocol<TCodec>
Custom event that can be received from the outside.
§type OutEvent = Event<TCodec>
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>
type Error = ConnectionHandlerUpgrErr<Error>
The type of errors returned by
ConnectionHandler::poll
.§type InboundProtocol = ResponseProtocol<TCodec>
type InboundProtocol = ResponseProtocol<TCodec>
The inbound upgrade for the protocol(s) used by the handler.
§type OutboundProtocol = RequestProtocol<TCodec>
type OutboundProtocol = RequestProtocol<TCodec>
The outbound upgrade for the protocol(s) used by the handler.
§type OutboundOpenInfo = RequestId
type OutboundOpenInfo = RequestId
The type of additional information passed to an
OutboundSubstreamRequest
.§type InboundOpenInfo = RequestId
type InboundOpenInfo = RequestId
The type of additional information returned from
listen_protocol
.source§fn listen_protocol(
&self,
) -> SubstreamProtocol<Self::InboundProtocol, Self::InboundOpenInfo>
fn listen_protocol( &self, ) -> SubstreamProtocol<Self::InboundProtocol, Self::InboundOpenInfo>
The
InboundUpgrade
to apply on inbound
substreams to negotiate the desired protocols. Read moresource§fn on_behaviour_event(&mut self, request: Self::InEvent)
fn on_behaviour_event(&mut self, request: Self::InEvent)
Informs the handler about an event from the
NetworkBehaviour
.source§fn connection_keep_alive(&self) -> KeepAlive
fn connection_keep_alive(&self) -> KeepAlive
Returns until when the connection should be kept alive. Read more
source§fn poll(

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>, )
source§fn map_in_event<TNewIn, TMap>(self, map: TMap) -> MapInEvent<Self, TNewIn, TMap>
fn map_in_event<TNewIn, TMap>(self, map: TMap) -> MapInEvent<Self, TNewIn, TMap>
Adds a closure that turns the input event into something else.
source§fn map_out_event<TMap, TNewOut>(self, map: TMap) -> MapOutEvent<Self, TMap>
fn map_out_event<TMap, TNewOut>(self, map: TMap) -> MapOutEvent<Self, TMap>
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. Read moreAuto Trait Implementations§
