Struct sc_network::peer_info::PeerInfoBehaviour

pub struct PeerInfoBehaviour { /* private fields */ }

Implementation of NetworkBehaviour that holds information about peers in cache.

Implementations

impl PeerInfoBehaviour

pub fn new( user_agent: String, local_public_key: PublicKey, external_addresses: Arc<Mutex<HashSet<Multiaddr>>> ) -> Self

Builds a new PeerInfoBehaviour.

pub fn node(&self, peer_id: &PeerId) -> Option<Node<'_>>

Borrows self and returns a struct giving access to the information about a node.

Returns None if we don’t know anything about this node. Always returns Some for nodes we’re connected to, meaning that if None is returned then we’re not connected to that node.

Trait Implementations

impl NetworkBehaviour for PeerInfoBehaviour

type ConnectionHandler = IntoConnectionHandlerSelect<<Behaviour as NetworkBehaviour>::ConnectionHandler, <Behaviour as NetworkBehaviour>::ConnectionHandler>

Handler for all the protocols the network behaviour supports.

type OutEvent = PeerInfoEvent

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

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

Callback that is invoked for every outbound connection attempt.

fn handle_established_inbound_connection( &mut self, connection_id: ConnectionId, peer: PeerId, local_addr: &Multiaddr, remote_addr: &Multiaddr ) -> Result<THandler<Self>, ConnectionDenied>

Callback that is invoked for every established inbound connection.

fn handle_established_outbound_connection( &mut self, connection_id: ConnectionId, peer: PeerId, addr: &Multiaddr, role_override: Endpoint ) -> Result<THandler<Self>, ConnectionDenied>

Callback that is invoked for every established outbound connection.

fn on_swarm_event(&mut self, event: FromSwarm<'_, Self::ConnectionHandler>)

Informs the behaviour about an event from the Swarm.

fn on_connection_handler_event( &mut self, peer_id: PeerId, connection_id: ConnectionId, event: THandlerOutEvent<Self> )

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

fn poll( &mut self, cx: &mut Context<'_>, params: &mut impl PollParameters ) -> Poll<ToSwarm<Self::OutEvent, THandlerInEvent<Self>>>

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

👎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.
