Struct sc_peerset::Peerset

impl Peerset

pub fn from_config(config: PeersetConfig) -> (Self, PeersetHandle)

Builds a new peerset from the given configuration.

pub fn reserved_peers(&self, set_id: SetId) -> impl Iterator<Item = &PeerId>

Returns the list of reserved peers.

pub fn add_to_peers_set(&mut self, set_id: SetId, peer_id: PeerId)

Adds a node to the given set. The peerset will, if possible and not already the case, try to connect to it.

Note: This has the same effect as PeersetHandle::add_to_peers_set.

pub fn incoming(&mut self, set_id: SetId, peer_id: PeerId, index: IncomingIndex)

Indicate that we received an incoming connection. Must be answered either with a corresponding Accept or Reject, except if we were already connected to this peer.

Note that this mechanism is orthogonal to Connect/Drop. Accepting an incoming connection implicitly means Connect, but incoming connections aren’t cancelled by dropped.

pub fn dropped(&mut self, set_id: SetId, peer_id: PeerId, reason: DropReason)

Indicate that we dropped an active connection with a peer, or that we failed to connect.

Must only be called after the PSM has either generated a Connect message with this PeerId, or accepted an incoming connection with this PeerId.

pub fn report_peer(&mut self, peer_id: PeerId, score_diff: ReputationChange)

Reports an adjustment to the reputation of the given peer.

pub fn debug_info(&mut self) -> Value

Produces a JSON object containing the state of the peerset manager, for debugging purposes.

pub fn num_discovered_peers(&self) -> usize

Returns the number of peers that we have discovered.
