Functions

func Wrap

func Wrap(errs []error) error

Wrap takes a slice of errors and returns a single error that encapsulates those underlying errors. If the slice is nil or empty it returns nil. If the slice only contains a single element, that error is returned directly. When more than one error is wrapped, the Error() string is a concatenation of the Error() values of all underlying errors.

Example
someFunc := func() error {
	return errors.New("doh")
}

var errs []error
for i := 0; i < 2; i++ {
	if err := someFunc(); err != nil {
		errs = append(errs, err)
	}
	fmt.Println(Wrap(errs).Error())
}
Output:

doh
[doh, doh]
