let mut iter = suffix.iter();
assert_eq!(iter.next().unwrap(), (&chars[..4], 2)); // abra
assert_eq!(iter.next(), Some((&chars[..1], 5))); // a
assert_eq!(iter.next(), Some((&chars[1..4], 2))); // bra
assert_eq!(iter.next(), Some((&chars[2..4], 2))); // ra
assert_eq!(iter.next(), Some((&chars[..0], 11))); // ''
assert_eq!(iter.next(), None);
