Function rot

Source 
pub fn rot(mode: Mode, inputs: &[u8], rotation: u8) -> Vec<u8>
Expand description

Transform any input to rot

use nrot::{rot, Mode};
let rotation = 13;

let input = b"Hello, World!";
let result = b"Uryyb, Jbeyq!";
let encrypted = rot(Mode::Encrypt, input, rotation);
assert_eq!(result.as_slice(), &encrypted);

let input = b"Uryyb, Jbeyq!";
let result = b"Hello, World!";
let encrypted = rot(Mode::Decrypt, input, rotation);
assert_eq!(result.as_slice(), &encrypted);
