Struct libp2p::mdns::Behaviour

pub struct Behaviour<P>where
    P: Provider,{ /* private fields */ }

A NetworkBehaviour for mDNS. Automatically discovers peers on the local network and adds them to the topology.

Implementations

impl<P> Behaviour<P>where P: Provider,

pub fn new(config: Config, local_peer_id: PeerId) -> Result<Behaviour<P>, Error>

Builds a new Mdns behaviour.

pub fn has_node(&self, peer_id: &PeerId) -> bool

Returns true if the given PeerId is in the list of nodes discovered through mDNS.

pub fn discovered_nodes(&self) -> impl ExactSizeIterator

Returns the list of nodes that we have discovered through mDNS and that are not expired.

pub fn expire_node(&mut self, peer_id: &PeerId)

Expires a node before the ttl.

Trait Implementations

impl<P> Debug for Behaviour<P>where P: Debug + Provider, <P as Provider>::Watcher: Debug, <P as Provider>::Socket: Debug, <P as Provider>::Timer: Debug,

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

Formats the value using the given formatter.

impl<P> NetworkBehaviour for Behaviour<P>where P: Provider,

type ConnectionHandler = ConnectionHandler

Handler for all the protocols the network behaviour supports.

type OutEvent = Event

Event generated by the NetworkBehaviour and that the swarm will report back.

fn handle_established_inbound_connection( &mut self, _: ConnectionId, _: PeerId, _: &Multiaddr, _: &Multiaddr ) -> Result<<<Behaviour<P> as NetworkBehaviour>::ConnectionHandler as IntoConnectionHandler>::Handler, ConnectionDenied>

Callback that is invoked for every established inbound connection.

fn handle_pending_outbound_connection( &mut self, _connection_id: ConnectionId, maybe_peer: Option<PeerId>, _addresses: &[Multiaddr], _effective_role: Endpoint ) -> Result<Vec<Multiaddr, Global>, ConnectionDenied>

Callback that is invoked for every outbound connection attempt.

fn handle_established_outbound_connection( &mut self, _: ConnectionId, _: PeerId, _: &Multiaddr, _: Endpoint ) -> Result<<<Behaviour<P> as NetworkBehaviour>::ConnectionHandler as IntoConnectionHandler>::Handler, ConnectionDenied>

Callback that is invoked for every established outbound connection.

fn on_connection_handler_event( &mut self, _: PeerId, _: ConnectionId, ev: <<<Behaviour<P> as NetworkBehaviour>::ConnectionHandler as IntoConnectionHandler>::Handler as ConnectionHandler>::OutEvent )

Informs the behaviour about an event generated by the ConnectionHandler dedicated to the peer identified by peer_id. for the behaviour.

fn on_swarm_event( &mut self, event: FromSwarm<'_, <Behaviour<P> as NetworkBehaviour>::ConnectionHandler> )

Informs the behaviour about an event from the Swarm.

fn poll( &mut self, cx: &mut Context<'_>, _: &mut impl PollParameters ) -> Poll<ToSwarm<<Behaviour<P> as NetworkBehaviour>::OutEvent, <<<Behaviour<P> as NetworkBehaviour>::ConnectionHandler as IntoConnectionHandler>::Handler as ConnectionHandler>::InEvent>>

Polls for things that swarm should do.

fn new_handler(&mut self) -> Self::ConnectionHandler

👎Deprecated since 0.42.0: Use one or more of NetworkBehaviour::{handle_pending_inbound_connection,handle_established_inbound_connection,handle_pending_outbound_connection,handle_established_outbound_connection} instead.

Creates a new ConnectionHandler for a connection with a peer.

fn handle_pending_inbound_connection( &mut self, _connection_id: ConnectionId, _local_addr: &Multiaddr, _remote_addr: &Multiaddr ) -> Result<(), ConnectionDenied>

Callback that is invoked for every new inbound connection.

fn addresses_of_peer(&mut self, _: &PeerId) -> Vec<Multiaddr, Global>

👎Deprecated: Use NetworkBehaviour::handle_pending_outbound_connection instead.

Addresses that this behaviour is aware of for this specific peer, and that may allow reaching the peer.
