Functions

func BaseUUID

func BaseUUID() string

BaseUUID generate uuid by base64 encoding

func BytesUUID

func BytesUUID() []byte

BytesUUID generate google/uuid as string

func HexUUID

func HexUUID(upper bool) string

HexUUID generate uuid by hex encoding

func ShortID

func ShortID(n int) string

ShortID generate a random string with length n. If n<=0 it use n as default length(8). NOTE: we suggest n>=8, too short id with higher risk of collision.

func ShortIDWithDic

func ShortIDWithDic(n int, dic string, headDicLen int) (string, error)

ShortIDWithDic generate a shortID with dictionary. headDicLen is the length of first byte use. NOTE: it will panic if dic is empty or headDicLen overflow dic.

func ShortIDWithError

func ShortIDWithError(n int) (string, error)

ShortIDWithError generate a random string with length n

func String

func String(n int) string

String Generate n length string

func StringUUID

func StringUUID() string

StringUUID generate google/uuid as string

func UpperShortID

func UpperShortID(n int) string

UpperShortID generate a random string with length n. If n<=0 it use n as default length(8). NOTE: we suggest n>=8, too short id with higher risk of collision. NOTE: it with much more probability to duplicate compare to ShortID.

func WithPrefix

func WithPrefix(id string, prefix string) string

WithPrefix add prefix to id if prefix is not empty
