type Service

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

Service:

• maintains connection with vanguard chain
• handles vanguard subscription for consensus info.
• sends new consensus info to all pandora subscribers.
• maintains consensusInfoDB to store the coming consensus info from vanguard.

func NewService

func NewService(
	ctx context.Context,
	vanEndpoint string,
	vanGRPCEndpoint string,

	consensusInfoAccessDB db.ConsensusInfoAccessDB,
	vanguardHeaderHashDB db.VanguardHeaderHashDB,
	dialRPCFn DialRPCFn,
	dialGRPCFn DIALGRPCFn,
) (*Service, error)

NewService creates new service with vanguard endpoint, vanguard namespace and consensusInfoDB

func SetupVanguardSvc

func SetupVanguardSvc(
	ctx context.Context,
	t *testing.T,
	dialRPCFn DialRPCFn,
	dialGRPCFn DIALGRPCFn,
) (*Service, *mocks)

SetupVanguardSvc creates vanguard client service with mocked database

func (*Service) OnNewConsensusInfo

func (s *Service) OnNewConsensusInfo(ctx context.Context, consensusInfo *types.MinimalEpochConsensusInfo)

OnNewConsensusInfo :

• sends the new consensus info to all subscribed pandora clients
• store consensus info into cache as well as into kv consensusInfoDB

func (*Service) OnNewPendingVanguardBlock
