Struct libp2p::swarm::handler::multi::MultiHandler

pub struct MultiHandler<K, H> { /* private fields */ }

A ConnectionHandler for multiple ConnectionHandlers of the same type.

Implementations

impl<K, H> MultiHandler<K, H>

where K: Clone + Debug + Hash + Eq + Send + 'static, H: ConnectionHandler,

pub fn try_from_iter<I>( iter: I ) -> Result<MultiHandler<K, H>, DuplicateProtonameError>

where I: IntoIterator<Item = (K, H)>,

Create and populate a MultiHandler from the given handler iterator.

It is an error for any two protocols handlers to share the same protocol name.

Trait Implementations

impl<K, H> Clone for MultiHandler<K, H>

where K: Clone, H: Clone,

fn clone(&self) -> MultiHandler<K, H>

Returns a copy of the value.

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

impl<K, H> ConnectionHandler for MultiHandler<K, H>

type FromBehaviour = (K, <H as ConnectionHandler>::FromBehaviour)

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

type ToBehaviour = (K, <H as ConnectionHandler>::ToBehaviour)

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

type InboundProtocol = Upgrade<K, <H as ConnectionHandler>::InboundProtocol>

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

type OutboundProtocol = <H as ConnectionHandler>::OutboundProtocol

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

type InboundOpenInfo = Info<K, <H as ConnectionHandler>::InboundOpenInfo>

The type of additional information returned from listen_protocol.

type OutboundOpenInfo = (K, <H as ConnectionHandler>::OutboundOpenInfo)

The type of additional information passed to an OutboundSubstreamRequest.

fn listen_protocol( &self ) -> SubstreamProtocol<<MultiHandler<K, H> as ConnectionHandler>::InboundProtocol, <MultiHandler<K, H> as ConnectionHandler>::InboundOpenInfo>

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

fn on_connection_event( &mut self, event: ConnectionEvent<'_, <MultiHandler<K, H> as ConnectionHandler>::InboundProtocol, <MultiHandler<K, H> as ConnectionHandler>::OutboundProtocol, <MultiHandler<K, H> as ConnectionHandler>::InboundOpenInfo, <MultiHandler<K, H> as ConnectionHandler>::OutboundOpenInfo> )

fn on_behaviour_event( &mut self, _: <MultiHandler<K, H> as ConnectionHandler>::FromBehaviour )

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<<MultiHandler<K, H> as ConnectionHandler>::OutboundProtocol, <MultiHandler<K, H> as ConnectionHandler>::OutboundOpenInfo, <MultiHandler<K, H> as ConnectionHandler>::ToBehaviour>>

Should behave like Stream::poll().

fn poll_close( &mut self, cx: &mut Context<'_> ) -> Poll<Option<<MultiHandler<K, H> as ConnectionHandler>::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>,

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<K, H> Debug for MultiHandler<K, H>

where K: Debug + Eq + Hash, H: Debug,

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

fn into_iter(self) -> <MultiHandler<K, H> as IntoIterator>::IntoIter

Creates an iterator from a value.
