Function ascii_converter::decimal_to_hexadecimal

pub fn decimal_to_hexadecimal(dec_vec: &Vec<u8>) -> Result<Vec<String>, String>

This function is passed decimal numbers and it then returns the hexadecimal representation.

Takes in a Vec<u8> where each value is a ascii values decimal number then will convert that to hexadecimal numbers which are returned as Vec<String>.

If a number passed in is above 126 an error will be thrown.

Example

 
use ascii_converter::*;
 
let input = vec![72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33];

let expected = vec![
   "48".to_string(),
   "65".to_string(),
   "6C".to_string(),
   "6C".to_string(),
   "6F".to_string(),
   "20".to_string(),
   "77".to_string(),
   "6F".to_string(),
   "72".to_string(),
   "6C".to_string(),
   "64".to_string(),
   "21".to_string()
];

assert_eq!(decimal_to_hexadecimal(&input).unwrap(), expected);
