Function ascii_converter::binary_to_hexadecimal

pub fn binary_to_hexadecimal(bin_vec: &Vec<u32>) -> Result<Vec<String>, String>

This function changes the binary number passed into a hexadecimal value.

This function takes a &Vec<u32> where each element should be a binary number. the input is converted to hexadecimal numbers and returned in the form of Vec<String>.

If the number passed in isn’t a 1 or 0 an error will be throw.

Example

use ascii_converter::*;
 
let input = vec! [1001000, 1100101, 1101100, 1101100, 1101111, 100000, 1110111, 1101111, 1110010, 1101100, 1100100, 100001];

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!(binary_to_hexadecimal(&input).unwrap(), expected)
