Function rocket_dyn_templates::minijinja::filters::slice

pub fn slice(
    state: &State<'_, '_>,
    value: Value,
    count: usize,
    fill_with: Option<Value>
) -> Result<Value, Error>

Slice an iterable and return a list of lists containing those items.

Useful if you want to create a div containing three ul tags that represent columns:

<div class="columnwrapper">
{% for column in items|slice(3) %}
  <ul class="column-{{ loop.index }}">
  {% for item in column %}
    <li>{{ item }}</li>
  {% endfor %}
  </ul>
{% endfor %}
</div>

If you pass it a second argument it’s used to fill missing values on the last iteration.
