var (
	// MaxSafeJSInt represents max value which JS support
	// It is used for smartContract fields
	// Our staking repo is written in JS, as are many other clients
	// If we use higher value JS will not be able to parse it
	MaxSafeJSInt = uint64(math.Pow(2, 53) - 2)

Functions

func ConvertUnmarshalledInt

func ConvertUnmarshalledInt(x interface{}) (int64, error)

func DirectoryExists

func DirectoryExists(directoryPath string) bool

DirectoryExists checks if the directory at the specified path exists

func GetTerminationSignalCh

func GetTerminationSignalCh() <-chan os.Signal

GetTerminationSignalCh returns a channel to emit signals by ctrl + c

func Max

func Max(a, b uint64) uint64

Max returns the strictly bigger number

func Min

Min returns the strictly lower number

func PadLeftOrTrim

func PadLeftOrTrim(bb []byte, size int) []byte

PadLeftOrTrim left-pads the passed in byte array to the specified size, or trims the array if it exceeds the passed in size

func SetupDataDir

func SetupDataDir(dataDir string, paths []string) error

SetupDataDir sets up the data directory and the corresponding sub-directories
