Trait Implementations

impl Clone for DummyConnectionHandler

fn clone(&self) -> DummyConnectionHandler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConnectionHandler for DummyConnectionHandler

type InEvent = Void

Custom event that can be received from the outside.

type OutEvent = Void

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

type Error = Void

The type of errors returned by ConnectionHandler::poll.

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 OutboundOpenInfo = Void

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<<DummyConnectionHandler as ConnectionHandler>::InboundProtocol, <DummyConnectionHandler as ConnectionHandler>::InboundOpenInfo>

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

fn inject_fully_negotiated_inbound(
    &mut self,
    _: <<DummyConnectionHandler as ConnectionHandler>::InboundProtocol as InboundUpgrade<Negotiated<SubstreamBox>>>::Output,
    _: <DummyConnectionHandler as ConnectionHandler>::InboundOpenInfo
)

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

fn inject_fully_negotiated_outbound(
    &mut self,
    _: <<DummyConnectionHandler as ConnectionHandler>::OutboundProtocol as OutboundUpgrade<Negotiated<SubstreamBox>>>::Output,
    v: <DummyConnectionHandler as ConnectionHandler>::OutboundOpenInfo
)

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

fn inject_event(
    &mut self,
    v: <DummyConnectionHandler as ConnectionHandler>::InEvent
)

Injects an event coming from the outside in the handler.

fn inject_address_change(&mut self, _: &Multiaddr)

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

fn inject_dial_upgrade_error(
    &mut self,
    _: <DummyConnectionHandler as ConnectionHandler>::OutboundOpenInfo,
    _: ConnectionHandlerUpgrErr<<<DummyConnectionHandler as ConnectionHandler>::OutboundProtocol as OutboundUpgrade<Negotiated<SubstreamBox>>>::Error>
)

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

fn inject_listen_upgrade_error(
    &mut self,
    _: <DummyConnectionHandler as ConnectionHandler>::InboundOpenInfo,
    _: ConnectionHandlerUpgrErr<<<DummyConnectionHandler as ConnectionHandler>::InboundProtocol as InboundUpgrade<Negotiated<SubstreamBox>>>::Error>
)

Indicates to the handler that upgrading an inbound 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,
    _: &mut Context<'_>
) -> Poll<ConnectionHandlerEvent<<DummyConnectionHandler as ConnectionHandler>::OutboundProtocol, <DummyConnectionHandler as ConnectionHandler>::OutboundOpenInfo, <DummyConnectionHandler as ConnectionHandler>::OutEvent, <DummyConnectionHandler as ConnectionHandler>::Error>>

Should behave like Stream::poll().

fn map_in_event<TNewIn, TMap>(self, map: TMap) -> MapInEvent<Self, TNewIn, TMap>where
    Self: Sized,
    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
    Self: Sized,
    TMap: FnMut(Self::OutEvent) -> 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 Debug for DummyConnectionHandler

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

Formats the value using the given formatter.

impl Default for DummyConnectionHandler

fn default() -> DummyConnectionHandler

Returns the “default value” for a type.
