pub fn namespace(defaults: Option<Value>) -> Result<Value, Error>Expand description
Creates a new container that allows attribute assignment using the {% set %} tag.
{% set ns = namespace() %}
{% set ns.foo = 'bar' %}The main purpose of this is to allow carrying a value from within a loop body
to an outer scope. Initial values can be provided as a dict, as keyword arguments,
or both (same behavior as dict).
