Types

type Config

type Config struct {
	common.AllGetsServer

	Ctx                 *snow.ConsensusContext
	VM                  block.ChainVM
	Sender              common.Sender
	Validators          validators.Manager
	ConnectedValidators tracker.Peers
	Params              snowball.Parameters
	Consensus           snowman.Consensus
	PartialSync         bool
}

Config wraps all the parameters needed for a snowman engine

type Engine

type Engine struct {
	Config

	// list of NoOpsHandler for messages dropped by engine
	common.StateSummaryFrontierHandler
	common.AcceptedStateSummaryHandler
	common.AcceptedFrontierHandler
	common.AcceptedHandler
	common.AncestorsHandler
	common.AppHandler
	validators.Connector
	// contains filtered or unexported fields
}

Engine implements the Engine interface by attempting to fetch all Engine dependencies.
