Functions

func ByteSize

func ByteSize(bytes uint64) string

ByteSize returns a human-readable byte string of the form 10M, 12.5K, and so forth. The following units are available:

E: Exabyte
P: Petabyte
T: Terabyte
G: Gigabyte
M: Megabyte
K: Kilobyte
B: Byte

The unit that results in the smallest number greater than or equal to 1 is always chosen.

func IpFromHostname

func IpFromHostname(enableIpV6 bool) (ip string, err error)

IpFromHostname 通过host获取ip列表中的第一个

func ParseTime

func ParseTime(value string) (result time.Time, err error)

func ToBytes

func ToBytes(s string) (uint64, error)

ToBytes parses a string formatted by ByteSize as bytes. Note binary-prefixed and SI prefixed units both mean a base-2 units KB = K = KiB = 1024 MB = M = MiB = 1024 * K GB = G = GiB = 1024 * M TB = T = TiB = 1024 * G PB = P = PiB = 1024 * T EB = E = EiB = 1024 * P

func ToMegabytes

func ToMegabytes(s string) (uint64, error)

ToMegabytes parses a string formatted by ByteSize as megabytes.

func ValidateFieldMessage

func ValidateFieldMessage(_type reflect.Type, exp string) (key string, msg string)

func ValidateRegisterDefault

func ValidateRegisterDefault(validate *validator.Validate)

func ValidateRegisterNotBlank

func ValidateRegisterNotBlank(validate *validator.Validate)

func ValidateRegisterNotEmpty

func ValidateRegisterNotEmpty(validate *validator.Validate)

func ValidateRegisterRegex

func ValidateRegisterRegex(validate *validator.Validate)
