type InboundOpenInfo = (<TProto1 as ProtocolsHandler>::InboundOpenInfo, <TProto2 as ProtocolsHandler>::InboundOpenInfo)

The type of additional information returned from listen_protocol.

pub fn listen_protocol(
    &self
) -> SubstreamProtocol<<ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InboundProtocol, <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InboundOpenInfo>

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

pub fn inject_fully_negotiated_outbound(
    &mut self,
    protocol: <<ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutboundProtocol as OutboundUpgradeSend>::Output,
    endpoint: <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutboundOpenInfo
)

Injects the output of a successful upgrade on a new outbound substream.

pub fn inject_fully_negotiated_inbound(
    &mut self,
    protocol: <<ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InboundProtocol as InboundUpgradeSend>::Output,
    <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InboundOpenInfo
)

Injects the output of a successful upgrade on a new inbound substream.

pub fn inject_event(
    &mut self,
    event: <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InEvent
)

Injects an event coming from the outside in the handler.

pub fn inject_address_change(&mut self, new_address: &Multiaddr)

Notifies the handler of a change in the address of the remote.

pub fn inject_dial_upgrade_error(
    &mut self,
    info: <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutboundOpenInfo,
    error: ProtocolsHandlerUpgrErr<<<ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutboundProtocol as OutboundUpgradeSend>::Error>
)

Indicates to the handler that upgrading an outbound substream to the given protocol has failed.

pub fn inject_listen_upgrade_error(
    &mut self,
    <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InboundOpenInfo,
    error: ProtocolsHandlerUpgrErr<<<ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::InboundProtocol as InboundUpgradeSend>::Error>
)

Indicates to the handler that upgrading an inbound substream to the given protocol has failed.

pub fn connection_keep_alive(&self) -> KeepAlive

Returns until when the connection should be kept alive.

pub fn poll(
    &mut self,
    cx: &mut Context<'_>
) -> Poll<ProtocolsHandlerEvent<<ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutboundProtocol, <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutboundOpenInfo, <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::OutEvent, <ProtocolsHandlerSelect<TProto1, TProto2> as ProtocolsHandler>::Error>>

Should behave like Stream::poll().

fn map_in_event<TNewIn, TMap>(self, map: TMap) -> MapInEvent<Self, TNewIn, TMap> where
    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
    TMap: FnMut(Self::OutEvent) -> TNewOut, 

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

fn select<TProto2>(
    self,
    other: TProto2
) -> ProtocolsHandlerSelect<Self, TProto2>

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

fn into_node_handler_builder(self) -> NodeHandlerWrapperBuilder<Self>

Creates a builder that allows creating a NodeHandler that handles this protocol exclusively.
