type Client ¶
type Client interface { // RequestAny synchronously sends request to the first connected peer that matches the specified minVersion in // random order. // A peer is considered a match if its version is greater than or equal to the specified minVersion // Returns errNoPeersMatchingVersion if no peer could be found matching specified version // and errRequestFailed if the request should be retried. RequestAny(minVersion *version.Application, request []byte) ([]byte, error) // Request synchronously sends request to the selected nodeID // Returns response bytes // Returns errRequestFailed if request should be retried Request(nodeID ids.NodeID, request []byte) ([]byte, error) // Gossip sends given gossip message to peers Gossip(gossip []byte) error }
Client defines ability to send request / response through the Network
type Network ¶
type Network interface { validators.Connector common.AppHandler // RequestAny synchronously sends request to the first connected peer that matches the specified minVersion in // random order. // A peer is considered a match if its version is greater than or equal to the specified minVersion // Returns an error if the request could not be sent to a peer with the desired [minVersion]. RequestAny(minVersion *version.Application, message []byte, handler message.ResponseHandler) error // Request sends message to given nodeID, notifying handler when there's a response or timeout Request(nodeID ids.NodeID, message []byte, handler message.ResponseHandler) error // Gossip sends given gossip message to peers Gossip(gossip []byte) error // Shutdown stops all peer channel listeners and marks the node to have stopped // n.Start() can be called again but the peers will have to be reconnected // by calling OnPeerConnected for each peer Shutdown() // SetGossipHandler sets the provided gossip handler as the gossip handler SetGossipHandler(handler message.GossipHandler) // SetRequestHandler sets the provided request handler as the request handler SetRequestHandler(handler message.RequestHandler) // Size returns the size of the network in number of connected peers Size() uint32 }
