enum.. versionadded:: 3.15
The ``enum`` function was added in Twig 3.15.
enum gives access to enums:
.. code-block:: twig
{# display one specific case of a backed enum #}
{{ enum('App\\CardSuite').Clubs.value }} {# "clubs" #}
{# display one specific case of a backed enum, with a dynamic name #}
{% set case_name = 'Spades' %}
{{ enum('App\\CardSuite').(case_name).name }} {# "Spades" #}
{# get all cases of an enum #}
{% for case in enum('App\\CardSuite').cases %}
{{ case.value }}
{% endfor %}
{# "clubs", "spades", "hearts", "diamonds" #}
{# get a specific case of an enum by value #}
{% set card_suite = enum('App\\CardSuite').from('hearts') %}
{{ card_suite.name }} {# "Hearts" #}
{{ card_suite.value }} {# "hearts" #}
{# call any methods of the enum class #}
{{ enum('App\\CardSuite').someMethod() }}
When using a string literal for the enum argument, it will be validated during compile time to be a valid enum name.
