Types

type Engine

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

func New

func New(
	log zerolog.Logger,
	net network.Network,
	me module.Local,
	engMetrics module.EngineMetrics,
	mempoolMetrics module.MempoolMetrics,
	cleaner storage.Cleaner,
	headers storage.Headers,
	payloads storage.Payloads,
	state protocol.MutableState,
	pending module.PendingBlockBuffer,
	follower module.HotStuffFollower,
	sync module.BlockRequester,
	tracer module.Tracer,
	opts ...compliance.Opt,
) (*Engine, error)

func (*Engine) Done

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

Done returns a done channel that is closed once the engine has fully stopped. For the consensus engine, we wait for hotstuff to finish.

func (*Engine) Process

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

Process processes the given event from the node with the given origin ID in a blocking manner. It returns the potential processing error when done.

func (*Engine) ProcessLocal

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

ProcessLocal processes an event originating on the local node.

func (*Engine) Ready

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

Ready returns a ready channel that is closed once the engine has fully started. For consensus engine, this is true once the underlying consensus algorithm has started.

func (*Engine) Submit

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

Submit submits the given event from the node with the given origin ID for processing in a non-blocking manner. It returns instantly and logs a potential processing error internally when done.

func (*Engine) SubmitLocal

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

SubmitLocal submits an event originating on the local node.
