Types

type Engine

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

func New

func New(
	log zerolog.Logger,
	net module.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,
) (*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(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(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.
