Function mles_utils::write_len_to_hdr

pub fn write_len_to_hdr(len: usize, hdrv: Vec<u8>) -> Vec<u8>

Write a length in network byte order to the header.

Example

use mles_utils::{write_hdr, write_len_to_hdr, do_hash, read_hdr_len, select_cid,
read_cid_from_hdr};

let hashstr = "A string".to_string();
let hashable = vec![hashstr];
let key = do_hash(&hashable); 
let cid = select_cid(key);
let mut hdr = write_hdr(515, cid);
let hdr = write_len_to_hdr(750, hdr);
assert_eq!(750, read_hdr_len(&hdr));
assert_eq!(cid, read_cid_from_hdr(&hdr));
