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.

Types

type Server

type Server struct {
	SyncChecker        sync.Checker
	Server             *grpc.Server
	BeaconDB           db.ReadOnlyDatabase

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) GetGenesis

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

GetGenesis fetches genesis chain information of Ethereum 2.0. Returns unix timestamp 0 if a genesis time has yet to be determined.

func (*Server) GetHost

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

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

func (*Server) GetPeer

func (ns *Server) GetPeer(ctx 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(ctx context.Context, _ *ptypes.Empty) (*ethpb.SyncStatus, error)

GetSyncStatus checks the current network sync status of the node.

func (*Server) GetVersion

func (ns *Server) GetVersion(ctx context.Context, _ *ptypes.Empty) (*ethpb.Version, error)

GetVersion checks the version information of the beacon node.

func (*Server) ListImplementedServices

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

ListPeers lists the peers connected to this node.
