	// contains filtered or unexported methods
}

Parameter is the interface for service parameters.

func WithAttestationDataProviders

func WithAttestationDataProviders(providers map[string]eth2client.AttestationDataProvider) Parameter

WithAttestationDataProviders sets the beacon block proposal providers.

func WithBlockRootToSlotCache

func WithBlockRootToSlotCache(cache cache.BlockRootToSlotProvider) Parameter

WithBlockRootToSlotCache sets the block root to slot cache.

func WithChainTime

func WithChainTime(chainTime chaintime.Service) Parameter

WithChainTime sets the chain time provider for this service.

func WithClientMonitor

func WithClientMonitor(monitor metrics.ClientMonitor) Parameter

WithClientMonitor sets the client monitor for the service.

func WithLogLevel

func WithLogLevel(logLevel zerolog.Level) Parameter

WithLogLevel sets the log level for the module.

func WithProcessConcurrency

func WithProcessConcurrency(concurrency int64) Parameter

func WithTimeout

func WithTimeout(timeout time.Duration) Parameter

WithTimeout sets the timeout for requests.

type Service

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

Service is the provider for attestation data.

func New

func New(_ context.Context, params ...Parameter) (*Service, error)

New creates a new attestation data strategy.

func (*Service) AttestationData

func (s *Service) AttestationData(ctx context.Context, slot phase0.Slot, committeeIndex phase0.CommitteeIndex) (*phase0.AttestationData, error)

AttestationData provides the best attestation data from a number of beacon nodes.
