How can I add custom classes for links into main menu in Drupal 8. This is template for my main menu called menu--main.html.twig

{% import _self as menus %}
{{ menus.menu_links(items, attributes, 0) }}

{% macro menu_links(items, attributes, menu_level) %}
  {% import _self as menus %}
  {% if items %}
    {% if menu_level == 0 %}
        <ul{{ attributes.addClass('main-nav') }}>

        {% for item in items %}
        <li{{ item.attributes.addClass('main-nav__item') }}>
            {{ link(item.title, item.url) }}
            {% if item.below %}
                {{ menus.menu_links(item.below, attributes, menu_level + 1) }}
            {% endif %}
        </li>
        {% endfor %}
    {% else %}
        <ul class="main-nav__sub js-nav-submenu ">

        {% for item in items %}
        <li{{ item.attributes.addClass('main-nav__sub-item') }}>
            {{ link(item.title, item.url) }}
            {% if item.below %}
                {{ menus.menu_links(item.below, attributes, menu_level + 1) }}
            {% endif %}
        </li>
        {% endfor %}
    {% endif %}
    </ul>
  {% endif %}
{% endmacro %}

And I need to achieve this result:

<ul class="main-nav">
  <li class="main-nav__item"><a class="main-nav__link main-nav__link--active" href="index.html">Úvod</a></li>
  <li class="main-nav__item"><a class="main-nav__link js-nav-submenu-toggler" href="#">O škole</a>
    <ul class="main-nav__sub js-nav-submenu">
      <li class="main-nav__sub-item"><a class="main-nav__sub-link" href="#">Aktuality</a></li>
      <li class="main-nav__sub-item"><a class="main-nav__sub-link " href="pedagogovia.html">Pedagógovia</a></li>
      <li class="main-nav__sub-item"><a class="main-nav__sub-link" href="#">Dokumenty</a></li>
      <li class="main-nav__sub-item"><a class="main-nav__sub-link " href="historia.html">História</a></li>
    </ul>
  </li>
  <li class="main-nav__item"><a class="main-nav__link" href="#">Informácie o štúdiu</a></li>
  <li class="main-nav__item"><a class="main-nav__link" href="#">Fotogaléria</a></li>
  <li class="main-nav__item"><a class="main-nav__link " href="kontakt.html">Kontakt</a></li>
</ul>

My problem is that I don't know how to set custom class for <a href=""> tags. Is there any way how can do it using link() function. In Drupal 7 is l() function but attributes aren't similar. l() has also third attribute with possibility to add options. Is it true, that link($title, $url)accepts only 2 parameters? Because I can't find the way how to send options for link($title, $url). I don't insit on link() function, so if there is some better way please let me know. I'm open to new ideas :)

Thanks

Just incase someone stumbles upon this, Martin's solve above breaks URL fragments as it overrides the URL options completely. The better approach is here:

{{ link(item.title, item.url.setOption('attributes', {'class' : 'main-nav__link'})) }}

I finally solved it using next syntax in Twig template

{{ link(item.title, item.url.setOptions({'set_active_class' : TRUE, 'attributes' : {'class' : 'main-nav__link'}})) }}
