Trait Implementations

    TProto1: Clone,
    TProto2: Clone, 

fn clone(&self) -> ProtocolsHandlerSelect<TProto1, TProto2>

Returns a copy of the value.

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

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

Formats the value using the given formatter.

impl<TProto1, TProto2> ProtocolsHandler for ProtocolsHandlerSelect<TProto1, TProto2> where
    TProto1: ProtocolsHandler,
    TProto2: ProtocolsHandler, 

type InEvent = EitherOutput<<TProto1 as ProtocolsHandler>::InEvent, <TProto2 as ProtocolsHandler>::InEvent>

Custom event that can be received from the outside.

type OutEvent = EitherOutput<<TProto1 as ProtocolsHandler>::OutEvent, <TProto2 as ProtocolsHandler>::OutEvent>

Custom event that can be produced by the handler and that will be returned to the outside.

type Error = EitherError<<TProto1 as ProtocolsHandler>::Error, <TProto2 as ProtocolsHandler>::Error>

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

type InboundProtocol = SelectUpgrade<SendWrapper<<TProto1 as ProtocolsHandler>::InboundProtocol>, SendWrapper<<TProto2 as ProtocolsHandler>::InboundProtocol>>

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

type OutboundProtocol = EitherUpgrade<SendWrapper<<TProto1 as ProtocolsHandler>::OutboundProtocol>, SendWrapper<<TProto2 as ProtocolsHandler>::OutboundProtocol>>

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

type OutboundOpenInfo = EitherOutput<<TProto1 as ProtocolsHandler>::OutboundOpenInfo, <TProto2 as ProtocolsHandler>::OutboundOpenInfo>

The type of additional information passed to an OutboundSubstreamRequest.

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

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

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.

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

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

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

Injects an event coming from the outside in the handler.

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 a substream to the given protocol has failed.

fn connection_keep_alive(&self) -> KeepAlive

Returns until when the connection should be kept alive.

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.

fn into_node_handler(self) -> NodeHandlerWrapper<Self>

Deprecated:

Use into_node_handler_builder instead

Builds an implementation of NodeHandler that handles this protocol exclusively.
