Struct sc_peerset::Peerset[][src]

pub struct Peerset { /* fields omitted */ }
Expand description

Side of the peer set manager owned by the network. In other words, the “receiving” side.

Implements the Stream trait and can be polled for messages. The Stream never ends and never errors.

Implementations

Builds a new peerset from the given configuration.

Returns the list of reserved peers.

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.

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.

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.

Reports an adjustment to the reputation of the given peer.

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

Returns the number of peers that we have discovered.
