Types

type Config

type Config struct {
	Ctx *snow.ConsensusContext
	common.AllGetsServer
	VM         vertex.DAGVM
	Manager    vertex.Manager
	Sender     common.Sender
	Validators validators.Set

	Params    avalanche.Parameters
	Consensus avalanche.Consensus
}

Config wraps all the parameters needed for an avalanche engine

type Engine

type Engine interface {
	common.Engine

	// GetVtx returns a vertex by its ID.
	// Returns an error if unknown.
	GetVtx(ctx context.Context, vtxID ids.ID) (avalanche.Vertex, error)
}

Engine describes the events that can occur on a consensus instance

func New

func New(config Config) (Engine, error)

func TraceEngine

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

type EngineTest

type EngineTest struct {
	common.EngineTest

	CantGetVtx bool
	GetVtxF    func(ctx context.Context, vtxID ids.ID) (avalanche.Vertex, error)
}

EngineTest is a test engine

func (*EngineTest) Default

func (e *EngineTest) Default(cant bool)

func (*EngineTest) GetVtx

func (e *EngineTest) GetVtx(ctx context.Context, vtxID ids.ID) (avalanche.Vertex, 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.
