Functions

func IsConvertFailed

func IsConvertFailed(err error) bool

IsConvertFailed check the error is a conversion error or not.

func IsInvalidValue

func IsInvalidValue(err error) bool

IsInvalidValue check the error is the value is invalid or not.

func IsNilError

func IsNilError(err error) bool

IsNilError check the error is nil or not.

func IsNotInitialized

func IsNotInitialized(err error) bool

IsNotInitialized check the error is the object is not initialized or not.

func IsRangeNotSatisfiable

Types

type DFGetError

type DFGetError struct {
	Code int
	Msg  string
}

DFGetError represents a error created by dfget.

func New

func New(code int, msg string) *DFGetError

New function creates a DFGetError.

func Newf

func Newf(code int, format string, a ...interface{}) *DFGetError

Newf function creates a DFGetError with a message according to a format specifier.

func (*DFGetError) Error

func (e *DFGetError) Error() string
