pub fn hexadecimal_to_decimal(hex_vec: Vec<String>) -> Result<Vec<u8>, String>

This function takes a hexadecimal number and returns the decimal number.

This function takes a Vec<String> to act as set of hexadecimal numbers. the function converts the input to a set of decimal numbers in the form of Vec<u8>.

If the number passed in isn’t a valid hexadecimal number an error will be thrown.

Example

use ascii_converter::*;

let input = 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()
];

let expected = vec![72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33];

assert_eq!(hexadecimal_to_decimal(input).unwrap(), expected);
