Functions

func CalcPositioningConstant 

func CalcPositioningConstant(upkeepID *utils.Big, registryAddress ethkey.EIP55Address) (int32, error)

CalcPositioningConstant calculates a positioning constant. The positioning constant is fixed because upkeepID and registryAddress are immutable

func LeastSignificant32 

func LeastSignificant32(num *big.Int) uint64

LeastSignificant32 returns the least significant 32 bits of the input as a big int

func ParseUpkeepId 

func ParseUpkeepId(upkeepIdStr string) (*big.Int, bool)

ParseUpkeepId parses the upkeep id input string to a big int pointer. It can handle the following 4 formats: 1. decimal format like 123471239047239047243709... 2. hex format like AbC13D354eFF... 3. 0x-prefixed hex like 0xAbC13D354eFF... 4. Upkeep-prefixed hex like UPxAbC13D354eFF...

func ValidatedKeeperSpec 

func ValidatedKeeperSpec(tomlString string) (job.Job, error)

ValidatedKeeperSpec analyses the tomlString passed as parameter and returns a newly-created Job if there are no validation errors inside the toml.
