Function cookie_factory::slice

pub fn slice<'a, S: 'a + AsRef<[u8]>>(data: S) -> impl SerializeFn<&'a mut [u8]>

writes a byte slice to the output

use cookie_factory::{length, slice};

let mut buf = [0u8; 100];

let len = {
  let (len, _) = length(slice(&b"abcd"[..]))(&mut buf[..]).unwrap();
  len
};

assert_eq!(len, 4usize);
assert_eq!(&buf[..4], &b"abcd"[..]);
