Types

type Config

type Config struct {
	ListenAddr        string
	MaxMsgSize        int  // In bytes
	RpcMetricsEnabled bool // enable GRPC metrics reporting
}

Config defines the configurable options for the gRPC server.

type Engine

type Engine struct {
	// contains filtered or unexported fields
}

Engine implements a gRPC server with a simplified version of the Observation API.

func New

func New(
	log zerolog.Logger,
	config Config,
	e *ingestion.Engine,
	blocks storage.Blocks,
	headers storage.Headers,
	state protocol.State,
	events storage.Events,
	exeResults storage.ExecutionResults,
	txResults storage.TransactionResults,
	chainID flow.ChainID) *Engine

New returns a new RPC engine.

func (*Engine) Done

func (e *Engine) Done() <-chan struct{}

Done returns a done channel that is closed once the engine has fully stopped. It sends a signal to stop the gRPC server, then closes the channel.

func (*Engine) Ready

func (e *Engine) Ready() <-chan struct{}

Ready returns a ready channel that is closed once the engine has fully started. The RPC engine is ready when the gRPC server has successfully started.
