func (t *RequestRoundTracker) Close() error

Close should be called after teardown of the OCR job relying on this tracker

func (*RequestRoundTracker) HandleLog 

func (t *RequestRoundTracker) HandleLog(lb log.Broadcast)

HandleLog complies with LogListener interface It is not thread safe

func (*RequestRoundTracker) IsV2Job 

func (t *RequestRoundTracker) IsV2Job() bool

func (*RequestRoundTracker) LatestRoundRequested 

func (t *RequestRoundTracker) LatestRoundRequested(_ context.Context, lookback time.Duration) (configDigest ocrtypes.ConfigDigest, epoch uint32, round uint8, err error)

LatestRoundRequested returns the configDigest, epoch, and round from the latest RoundRequested event emitted by the contract. LatestRoundRequested may or may not return a result if the latest such event was emitted in a block b such that b.timestamp < tip.timestamp - lookback.

If no event is found, LatestRoundRequested should return zero values, not an error. An error should only be returned if an actual error occurred during execution, e.g. because there was an error querying the blockchain or the database.

As an optimization, this function may also return zero values, if no RoundRequested event has been emitted after the latest NewTransmission event.
