Functions

func NewHTTPServer

func NewHTTPServer(
	grpcServer *grpc.Server,
	address string,
) *http.Server

NewHTTPServer creates and intializes a new HTTP GRPC proxy server

Types

type Config

type Config struct {
	GRPCListenAddr        string
	HTTPListenAddr        string
	ExecutionAddr         string
	CollectionAddr        string
	HistoricalAccessAddrs string
	MaxMsgSize            int // In bytes
}

Config defines the configurable options for the access node 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,
	state protocol.State,
	config Config,
	executionRPC execproto.ExecutionAPIClient,
	collectionRPC accessproto.AccessAPIClient,
	historicalAccessNodes []accessproto.AccessAPIClient,
	blocks storage.Blocks,
	headers storage.Headers,
	collections storage.Collections,
	transactions storage.Transactions,
	chainID flow.ChainID,
	transactionMetrics module.TransactionMetrics,
	collectionGRPCPort uint,
	retryEnabled bool,
	rpcMetricsEnabled bool,
) *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.

func (*Engine) SubmitLocal

func (e *Engine) SubmitLocal(event interface{})

SubmitLocal submits an event originating on the local node.

type HTTPHeader

type HTTPHeader struct {
	Key   string
	Value string
}
