Struct libp2p::mdns::Mdns

pub struct Mdns<TSubstream> { /* fields omitted */ }

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

Methods

impl<TSubstream> Mdns<TSubstream>

pub fn new() -> Result<Mdns<TSubstream>, 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.

Trait Implementations

impl<TSubstream> Debug for Mdns<TSubstream>

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

Formats the value using the given formatter.

impl<TSubstream> NetworkBehaviour for Mdns<TSubstream> where
    TSubstream: AsyncRead + AsyncWrite, 

type ProtocolsHandler = DummyProtocolsHandler<TSubstream>

Handler for all the protocols the network behaviour supports.

type OutEvent = MdnsEvent

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

fn new_handler(
    &mut self
) -> <Mdns<TSubstream> as NetworkBehaviour>::ProtocolsHandler

Creates a new ProtocolsHandler for a connection with a peer.

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

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

fn inject_connected(&mut self, PeerId, ConnectedPoint)

Indicates the behaviour that we connected to the node with the given peer id through the given endpoint.

fn inject_disconnected(&mut self, &PeerId, ConnectedPoint)

Indicates the behaviour that we disconnected from the node with the given peer id. The endpoint is the one we used to be connected to.

fn inject_node_event(
    &mut self,
    PeerId,
    _ev: <<Mdns<TSubstream> as NetworkBehaviour>::ProtocolsHandler as ProtocolsHandler>::OutEvent
)

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

fn poll<impl PollParameters>(
    &mut self,
    params: &mut impl PollParameters
) -> Async<NetworkBehaviourAction<<<Mdns<TSubstream> as NetworkBehaviour>::ProtocolsHandler as ProtocolsHandler>::InEvent, <Mdns<TSubstream> as NetworkBehaviour>::OutEvent>> where
    impl PollParameters: PollParameters, 

Polls for things that swarm should do.

fn inject_replaced(
    &mut self,
    peer_id: PeerId,
    closed_endpoint: ConnectedPoint,
    new_endpoint: ConnectedPoint
)

Indicates the behaviour that we replace the connection from the node with another.

fn inject_addr_reach_failure(
    &mut self,
    _peer_id: Option<&PeerId>,
    _addr: &Multiaddr,
    _error: &dyn Error
)

Indicates to the behaviour that we tried to reach an address, but failed.

fn inject_dial_failure(&mut self, _peer_id: &PeerId)

Indicates to the behaviour that we tried to dial all the addresses known for a node, but failed.

fn inject_new_listen_addr(&mut self, _addr: &Multiaddr)

Indicates to the behaviour that we have started listening on a new multiaddr.

fn inject_expired_listen_addr(&mut self, _addr: &Multiaddr)

Indicates to the behaviour that a new multiaddr we were listening on has expired, which means that we are no longer listening in it.

fn inject_new_external_addr(&mut self, _addr: &Multiaddr)

Indicates to the behaviour that we have discovered a new external address for us.

fn inject_listener_error(
    &mut self,
    _id: ListenerId,
    _err: &(dyn Error + 'static)
)

A listener experienced an error.

fn inject_listener_closed(&mut self, _id: ListenerId)

A listener closed.
