Types

type Config

type Config interface {
	MinIncomingConfirmations() uint32
	EvmGasLimitDefault() uint64
}

type Delegate

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

func NewDelegate

func NewDelegate(
	db *gorm.DB,
	ks keystore.Master,
	pr pipeline.Runner,
	porm pipeline.ORM,
	chainSet evm.ChainSet,
	lggr logger.Logger) *Delegate

func (*Delegate) AfterJobCreated

func (d *Delegate) AfterJobCreated(spec job.Job)

func (*Delegate) BeforeJobDeleted

func (d *Delegate) BeforeJobDeleted(spec job.Job)

func (*Delegate) JobType

func (d *Delegate) JobType() job.Type

func (*Delegate) ServicesForSpec

func (d *Delegate) ServicesForSpec(jb job.Job) ([]job.Service, error)

type GethKeyStore

type GethKeyStore interface {
	GetRoundRobinAddress(addresses ...common.Address) (common.Address, error)
}

type RandomnessRequestLog

type RandomnessRequestLog struct {
	KeyHash   common.Hash
	Seed      *big.Int // uint256
	JobID     common.Hash
	Sender    common.Address
	Fee       *assets.Link // uint256
	RequestID common.Hash
	Raw       RawRandomnessRequestLog
}

RandomnessRequestLog contains the data for a RandomnessRequest log, represented as compatible golang types.

func ParseRandomnessRequestLog

func ParseRandomnessRequestLog(log types.Log) (*RandomnessRequestLog, error)

ParseRandomnessRequestLog returns the RandomnessRequestLog corresponding to the raw logData

func RawRandomnessRequestLogToRandomnessRequestLog

func RawRandomnessRequestLogToRandomnessRequestLog(
	l *RawRandomnessRequestLog) *RandomnessRequestLog

func (*RandomnessRequestLog) ComputedRequestID

func (l *RandomnessRequestLog) ComputedRequestID() common.Hash

func (*RandomnessRequestLog) Equal

func (l *RandomnessRequestLog) Equal(ol RandomnessRequestLog) bool

Equal(ol) is true iff l is the same log as ol, and both represent valid RandomnessRequest logs.

func (*RandomnessRequestLog) RawData

func (l *RandomnessRequestLog) RawData() ([]byte, error)

RawData returns the raw bytes corresponding to l in a solidity log

This serialization does not include the JobID, because that's an indexed field.

type RawRandomnessRequestLog

type RawRandomnessRequestLog solidity_vrf_coordinator_interface.VRFCoordinatorRandomnessRequest

RawRandomnessRequestLog is used to parse a RandomnessRequest log into types go-ethereum knows about.
