Functions

func CatchCheckError

func CatchCheckError()

CatchCheckError catch the panic error throwing by CheckError. If func have another defer to catch recover(), put the defer before defer CatchCheckError. For example:

func myFunc() (err error) {
		defer func() {
			e := recover()
			if e != nil {
				err = fmt.Errorf("%s", e)
			}
		}()
		defer CatchCheckError()
		panic("abc")
	}

func CheckError

func CheckError(err error)

CheckError if err is not nil, the func call will return immediately at CheckError call. this should be worked with defer CatchCheckError()

func CheckError2

func CheckError2(v interface{}, err error) *gvalue.AnyValue

CheckError2 check the err and return the value if err is nil

func CheckError3

func CheckError3(v1 interface{}, v2 interface{}, err error) (*gvalue.AnyValue, *gvalue.AnyValue)

CheckError3 check the err and return the value if err is nil

func IsWaitTimeoutErr

func IsWaitTimeoutErr(e error) bool

func Recover

func Recover(f func(gcore.Error))

func Wait

func Wait(f func()) <-chan error

func WaitTimeout

func WaitTimeout(f func(), timeout time.Duration) error
