type OCRContractConfigSubscription 

type OCRContractConfigSubscription OCRContractTracker

OCRContractConfigSubscription only exists to comply with the ContractConfigSubscription interface, it's just a simple shell around OCRContractTracker that defines two methods

func (*OCRContractConfigSubscription) Close 

func (sub *OCRContractConfigSubscription) Close()

Close is a no-op since Subscribing/Unsubscribing is handled in the Start/Close methods of the OCRContractTracker

func (*OCRContractConfigSubscription) Configs 

func (sub *OCRContractConfigSubscription) Configs() <-chan ocrtypes.ContractConfig

Configs complies with ContractConfigSubscription interface

type OCRContractTracker added in v0.10.3 

type OCRContractTracker struct {
	utils.StartStopOnce
	// contains filtered or unexported fields
}

func (*OCRContractTracker) JobID added in v0.10.3

func (*OCRContractTracker) LatestBlockHeight added in v0.10.3 

func (t *OCRContractTracker) LatestBlockHeight(ctx context.Context) (blockheight uint64, err error)

func (*OCRContractTracker) LatestConfigDetails added in v0.10.3 

func (t *OCRContractTracker) LatestConfigDetails(ctx context.Context) (changedInBlock uint64, configDigest ocrtypes.ConfigDigest, err error)

func (*OCRContractTracker) LatestRoundRequested added in v0.10.3 

func (t *OCRContractTracker) 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.
