func (*Error) As

func (e *Error) As(target error) bool

As implement `As`

func (*Error) Error

No need to print wrapped error, `go` print it automatically

func (*Error) Is

func (e *Error) Is(target error) bool

Is implement `Is`

func (*Error) Unwrap

func (e *Error) Unwrap() error

Unwrap implement `Unwrap`
