Function cookie_factory::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

use cookie_factory::{many_ref, string};

let mut buf = [0u8; 100];

let data = vec!["abcd", "efgh", "ijkl"];
{
  let buf = many_ref(&data, string)(&mut buf[..]).unwrap();
  assert_eq!(buf.len(), 100 - 12);
}

assert_eq!(&buf[..12], &b"abcdefghijkl"[..]);
