Module codes_check_digits::luhn

The type CheckDigitAlgorithm provides an implementation of the Luhn Algorithm.

Example

use codes_check_digits::{luhn, Calculator};

let calculator = luhn::get_algorithm_instance();
assert!(calculator.is_valid("US0378331005"));
assert!(calculator.validate("US0378331005").is_ok());
assert_eq!(calculator.calculate("US037833100"), Ok(5));
