Trait Implementations

impl ConnectionHandler for Handler

type FromBehaviour = Command

A type representing the message(s) a NetworkBehaviour can send to a [ConnectionHandler] via ToSwarm::NotifyHandler

type ToBehaviour = Event

A type representing message(s) a [ConnectionHandler] can send to a NetworkBehaviour via [ConnectionHandlerEvent::NotifyBehaviour].

type Error = Error

The type of errors returned by [ConnectionHandler::poll].

type InboundProtocol = ReadyUpgrade<StreamProtocol>

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

type OutboundProtocol = ReadyUpgrade<StreamProtocol>

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

type OutboundOpenInfo = ()

The type of additional information passed to an OutboundSubstreamRequest.

type InboundOpenInfo = ()

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 connection_keep_alive(&self) -> KeepAlive

Returns until when the connection should be kept alive.

fn poll( &mut self, cx: &mut Context<'_>, ) -> Poll<ConnectionHandlerEvent<Self::OutboundProtocol, Self::OutboundOpenInfo, Self::ToBehaviour, Self::Error>>

Should behave like Stream::poll().

fn on_behaviour_event(&mut self, event: Self::FromBehaviour)

Informs the handler about an event from the NetworkBehaviour.

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::FromBehaviour>,

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::ToBehaviour) -> 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.
