Struct libp2p_swarm::dummy::ConnectionHandler

pub struct ConnectionHandler;

An implementation of ConnectionHandler that neither handles any protocols nor does it keep the connection alive.

Trait Implementations

impl Clone for ConnectionHandler

fn clone(&self) -> ConnectionHandler

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConnectionHandler for ConnectionHandler

type FromBehaviour = Void

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

type ToBehaviour = Void

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

type InboundProtocol = DeniedUpgrade

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

type OutboundProtocol = DeniedUpgrade

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

type InboundOpenInfo = ()

The type of additional information returned from listen_protocol.

type OutboundOpenInfo = Void

The type of additional information passed to an OutboundSubstreamRequest.

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, event: Self::FromBehaviour)

Informs the handler about an event from the NetworkBehaviour.

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

Should behave like Stream::poll().

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

fn connection_keep_alive(&self) -> bool

Returns whether the connection should be kept alive.

fn poll_close(&mut self, _: &mut Context<'_>) -> Poll<Option<Self::ToBehaviour>>

Gracefully close the ConnectionHandler.

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.
