func Multi(errs ...error) error

Multi combines multiple errors into one:

• If all errors are nil, it returns nil.

• If there is one non-nil error, it is returned.

• Otherwise, the return value is an error whose Error methods contain all the messages of all non-nil arguments.

If the input contains any error returned by Multi, such errors are flattened. The following two calls return the same value:

Multi(Multi(err1, err2), Multi(err3, err4))
Multi(err1, err2, err3, err4)
