export default (function ($el, binding) {
    /**
     * @var Errors $errors
     */
    var $errors = binding.value;
    if (!$el.attributes.name) {
        throw new Error('v-invalid directive requires `name` attribute on input.');
    }
    if ($errors.has($el.attributes.name.value)) {
        $el.classList.add('is-invalid');
    }
    else {
        $el.classList.remove('is-invalid');
    }
});
