Breadcrumb
The breadcrumb functions returns the \Anomaly\Streams\Platform\Ui\Breadcrumb\BreadcrumbCollection.
You can use this function to automatically generate a Bootstrap 3/4 breadcrumb:
{{ breadcrumb() }} // Returns Bootstrap breadcrumb
You can use the same function to generate your own breadcrumb:
<ol class="breadcrumb">
    {% for breadcrumb, url in breadcrumb() %}
        {% if loop.last %}
            <li class="breadcrumb-item active">{{ trans(breadcrumb) }}</li>
        {% else %}
            <li class="breadcrumb-item"><a href="{{ url }}">{{ trans(breadcrumb) }}</a></li>
        {% endif %}
    {% endfor %}
</ol>
