Types

type Engine

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

An Engine provides means of accessing data about execution state and broadcasts execution receipts to nodes in the network. Also generates and saves execution receipts

func New

func New(
	logger zerolog.Logger,
	tracer module.Tracer,
	net network.Network,
	state protocol.State,
	me module.Local,
	execState state.ReadOnlyExecutionState,
	metrics module.ExecutionMetrics,
	checkStakedAtBlock func(blockID flow.Identifier) (bool, error),
	chdpQueryTimeout uint,
	chdpDeliveryTimeout uint,
) (*Engine, error)

func (*Engine) BroadcastExecutionReceipt

func (e *Engine) BroadcastExecutionReceipt(ctx context.Context, receipt *flow.ExecutionReceipt) error

func (*Engine) Done

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

Done returns a channel that will close when the engine has successfully stopped.

func (*Engine) Process

func (e *Engine) Process(channel network.Channel, originID flow.Identifier, event interface{}) error

func (*Engine) ProcessLocal

func (e *Engine) ProcessLocal(event interface{}) error

func (*Engine) Ready

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

Ready returns a channel that will close when the engine has successfully started.

func (*Engine) Submit

func (e *Engine) Submit(channel network.Channel, originID flow.Identifier, event interface{})

func (*Engine) SubmitLocal

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

type ProviderEngine

type ProviderEngine interface {
	network.Engine
	BroadcastExecutionReceipt(context.Context, *flow.ExecutionReceipt) error
}
