Struct WithMatchingHelper

pub struct WithMatchingHelper;

Execute the inner template with the matching parameter, when matching key is equal to the first parameter {{#with_matching some_value matching_key1 context1 mateching_key2 context2 … }} Render the inverse template if no matching key was found
