Struct libp2p_swarm::handler::MapInEvent

pub struct MapInEvent<TConnectionHandler, TNewIn, TMap> { /* private fields */ }

Wrapper around a protocol handler that turns the input event into something else.

Trait Implementations

impl<TConnectionHandler, TMap, TNewIn> ConnectionHandler for MapInEvent<TConnectionHandler, TNewIn, TMap>

where TConnectionHandler: ConnectionHandler, TMap: Fn(TNewIn) -> Option<TConnectionHandler::FromBehaviour> + Send + 'static, TNewIn: Debug + Send + 'static,

type FromBehaviour = TNewIn

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

type ToBehaviour = <TConnectionHandler as ConnectionHandler>::ToBehaviour

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

type InboundProtocol = <TConnectionHandler as ConnectionHandler>::InboundProtocol

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

type OutboundProtocol = <TConnectionHandler as ConnectionHandler>::OutboundProtocol

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

type InboundOpenInfo = <TConnectionHandler as ConnectionHandler>::InboundOpenInfo

The type of additional information returned from listen_protocol.

type OutboundOpenInfo = <TConnectionHandler as ConnectionHandler>::OutboundOpenInfo

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: TNewIn)

Informs the handler about an event from the NetworkBehaviour.

fn connection_keep_alive(&self) -> bool

Returns whether the connection should be kept alive.

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

Should behave like Stream::poll().

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

Gracefully close the ConnectionHandler.

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.

impl<TConnectionHandler: Debug, TNewIn: Debug, TMap: Debug> Debug for MapInEvent<TConnectionHandler, TNewIn, TMap>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
