Functions

func AddPathSeparatorIfAbsent

func AddPathSeparatorIfAbsent(path string) string

func CreateDirIfNotExists

func CreateDirIfNotExists(dirname string) error

func CurrentTimeMillis

func CurrentTimeMillis() uint64

Returns the current Unix timestamp in milliseconds.

func CurrentTimeMillsWithTicker

func CurrentTimeMillsWithTicker() uint64

func CurrentTimeNano

func CurrentTimeNano() uint64

Returns the current Unix timestamp in nanoseconds.

func DecrementAndGetInt64

func DecrementAndGetInt64(v *int64) int64

func FileExists

func FileExists(name string) (b bool, err error)

func FilePosition

func FilePosition(file *os.File) (int64, error)

func Float64Equals

func Float64Equals(x, y float64) bool

func FormatDate

func FormatDate(tsMillis uint64) string

FormatDate formats Unix timestamp (ms) to date string

func FormatTimeMillis

func FormatTimeMillis(tsMillis uint64) string

FormatTimeMillis formats Unix timestamp (ms) to time string.

func IncrementAndGetInt64

func IncrementAndGetInt64(v *int64) int64

func IsBlank

func IsBlank(s string) bool

IsBlank checks whether the given string is blank.

func NewUuid

func NewUuid() string
