Documentation

Overview

Package node defines a gRPC node service implementation, providing useful endpoints for checking a node's sync status, peer info, genesis data, and version information.

Server defines a server implementation of the gRPC Node service, providing RPC endpoints for verifying a beacon node's sync status, genesis and version information, and services the node implements and runs.

func (*Server) GetETH1ConnectionStatus

func (ns *Server) GetETH1ConnectionStatus(_ context.Context, _ *empty.Empty) (*ethpb.ETH1ConnectionStatus, error)

GetETH1ConnectionStatus gets data about the ETH1 endpoints.

func (*Server) GetGenesis

func (ns *Server) GetGenesis(ctx context.Context, _ *empty.Empty) (*ethpb.Genesis, error)

GetGenesis fetches genesis chain information of Ethereum. Returns unix timestamp 0 if a genesis time has yet to be determined.

func (*Server) GetHealth

func (ns *Server) GetHealth(ctx context.Context, request *ethpb.HealthRequest) (*empty.Empty, error)

GetHealth checks the health of the node

func (*Server) GetHost

func (ns *Server) GetHost(_ context.Context, _ *empty.Empty) (*ethpb.HostData, error)

GetHost returns the p2p data on the current local and host peer.

func (*Server) GetPeer

func (ns *Server) GetPeer(_ context.Context, peerReq *ethpb.PeerRequest) (*ethpb.Peer, error)

GetPeer returns the data known about the peer defined by the provided peer id.

func (*Server) GetSyncStatus

func (ns *Server) GetSyncStatus(_ context.Context, _ *empty.Empty) (*ethpb.SyncStatus, error)

GetSyncStatus checks the current network sync status of the node.

func (*Server) GetVersion

func (_ *Server) GetVersion(_ context.Context, _ *empty.Empty) (*ethpb.Version, error)

GetVersion checks the version information of the beacon node.

func (*Server) ListImplementedServices

func (ns *Server) ListImplementedServices(_ context.Context, _ *empty.Empty) (*ethpb.ImplementedServices, error)

ListImplementedServices lists the services implemented and enabled by this node.

Any service not present in this list may return UNIMPLEMENTED or PERMISSION_DENIED. The server may also support fetching services by grpc reflection.

func (*Server) ListPeers

func (ns *Server) ListPeers(ctx context.Context, _ *empty.Empty) (*ethpb.Peers, error)

ListPeers lists the peers connected to this node.

func (*Server) StreamBeaconLogs

func (ns *Server) StreamBeaconLogs(_ *empty.Empty, stream ethpb.Health_StreamBeaconLogsServer) error

StreamBeaconLogs from the beacon node via a gRPC server-side stream. DEPRECATED: This endpoint doesn't appear to be used and have been marked for deprecation.
