Crate codes_check_digits

Source
Expand description

Provides tools for building different check-digit algorithms.

This package contains implementations of various check digit specifications, including ISO/IEC 7064:2003 Information technology — Security techniques — Check character systems.

§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));

§Features

  • gs1 - Adds the gs1 module containing algorithms for various codes such as EAN, GTIN, GLN, and UPC.
  • iso_7064 - Adds the iso_7064 module containing implementations of the variants defined in ISO/IEC 7064:2003.
  • luhn - Adds the luhn module containing an implementation of the Luhn Algorithm.
  • sedol - Adds the sedol module containing an implementation of the algorithm used in SEDOL numbers.
