Types

type Config

type Config struct {
	common.AllGetsServer

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

Config wraps all the parameters needed for a snowman engine

type Engine

type Engine interface {
	common.Engine
	block.Getter
}

Engine describes the events that can occur to a Snowman instance.

The engine is used to fetch, order, and decide on the fate of blocks. This engine runs the leaderless version of the Snowman consensus protocol. Therefore, the liveness of this protocol tolerant to O(sqrt(n)) Byzantine Nodes where n is the number of nodes in the network. Therefore, this protocol should only be run in a Crash Fault Tolerant environment, or in an environment where lose of liveness and manual intervention is tolerable.

func New added in v1.7.4

func New(config Config) (Engine, error)

func TraceEngine added in v1.9.1

func TraceEngine(engine Engine, tracer trace.Tracer) Engine

type EngineTest added in v1.7.5

type EngineTest struct {
	common.EngineTest

	CantGetBlock bool
	GetBlockF    func(context.Context, ids.ID) (snowman.Block, error)
}

EngineTest is a test engine

func (*EngineTest) Default added in v1.7.5

func (e *EngineTest) Default(cant bool)

func (*EngineTest) GetBlock added in v1.7.5

func (e *EngineTest) GetBlock(ctx context.Context, blkID ids.ID) (snowman.Block, error)

type Transitive

type Transitive struct {
	Config

	// list of NoOpsHandler for messages dropped by engine
	common.StateSummaryFrontierHandler
	common.AcceptedStateSummaryHandler
	common.AcceptedFrontierHandler
	common.AcceptedHandler
	common.AncestorsHandler
	common.AppHandler
	validators.Connector

	RequestID uint32
	// contains filtered or unexported fields
}

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