Function Is

error_1_13.go:21–35

Is detects whether the error is equal to a given error. Errors are considered equal by this function if they are matched by errors.Is or if their contained errors are matched through errors.Is.

(e error, original error)

// are considered equal by this function if they are matched by errors.Is
// or if their contained errors are matched through errors.Is.
