Function cookie_factory::many_ref

pub fn many_ref<'a, E, It, I, F, G, O>(
    items: I, 
    generator: F
) -> impl SerializeFn<O> + 'a where
    It: Iterator<Item = E> + Clone + 'a,
    I: IntoIterator<Item = E, IntoIter = It>,
    F: Fn(E) -> G + 'a,
    G: SerializeFn<O> + 'a,
    O: 'a, 

applies a generator over an iterator of values, and applies the serializers generated
