Function cookie_factory::multi::many_ref

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

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