Functions ¶

func AESDecrypt ¶

func AESDecrypt(text, key string) (string, error)

AESDecrypt Example of use

decrypted, err := AESDecrypt(encrypted, key)
if err != nil {
	fmt.Println("Error decrypting:", err)
	return
}
fmt.Println("Decrypted:", decrypted)

func AESEncrypt ¶

func AESEncrypt(text, key string) (string, error)

AESEncrypt Example of use

key := "myverystrongpasswordo32bitlength"
password := "mysecretpassword"

encrypted, err := AESEncrypt(password, key)
if err != nil {
	fmt.Println("Error encrypting:", err)
	return
}
fmt.Println("Encrypted:", encrypted)

func ByteFormat ¶

func ByteFormat(b int64) string

ByteFormat wraps global Bytes's Format function.

func ByteParse ¶

func ByteParse(val string) (int64, error)

ByteParse wraps global Bytes's Parse function.

func BytesToInt ¶

func BytesToInt(bys []byte) int

func BytesToInt64 ¶

func BytesToInt64(bys []byte) int64

func Co ¶

func Co(asyncFunc AsyncFunc, timeout time.Duration) error

Co Description of function usage

errCo := x.Co(func(c context.Context) error {
	return f.xxx(ctx, aa, bb)
}, x.CoTimeout)
defer func() {
	if errCo != nil {
		if errors.Is(errCo, x.ErrAsyncFuncTimeout) {
			elog.Warn("file_vo_fill_tags", elog.FieldCtxTid(ctx.Request.Context()), l.E(err))
		} else {
			elog.Error("file_vo_fill_tags", elog.FieldCtxTid(ctx.Request.Context()), l.E(err))
		}
	}
}()

func Decimal ¶

func Decimal(v float64) float64

func DownloadPictureBytes ¶

func DownloadPictureBytes(url string, timeout time.Duration) (res []byte, err error)

func Go(fn func())

Go goroutine

func Hash ¶

func Hash(s string) uint32

func I2S ¶

func I2S[T Int](i T) string

func InputCheck ¶

func InputCheck(input string) bool

func Int64ToBytes ¶

func Int64ToBytes(data int64) []byte

func IntToBytes ¶

func MergeLabels ¶

func MergeLabels(old map[string]string, new map[string]string) map[string]string

MergeLabels merge label the new map will overwrite the old one. e.g. new: {"foo": "newbar"} old: {"foo": "bar"} will return {"foo": "newbar"}

func Page ¶

func Page(from, to, size int64, fn func(from, to int64) error) error

Page parses the function call by size from to, with closed intervals. For example: from=0 to=100 size=10 then the function is called 10 times, each time with from=0 to=10, from=10 to=20, from=20 to=30, ... , from=90 to=100
