Validate Turkish national identification numbers (T.C. Kimlik No.).

The Turkish Identification Number (Türkiye Cumhuriyeti Kimlik Numarası) is an 11-digit number assigned to every citizen of Turkey, whose last two digits are check digits. A faithful Rust port of the algorithm used by python-stdnum.

• Zero dependencies, #![no_std]
• is_valid, validate, calc_check_digits, compact
• Differential-tested against python-stdnum (60k cases)

Usage

use tckimlik::{is_valid, validate, calc_check_digits};

assert!(is_valid("17291716060"));
assert!(!is_valid("17291716050")); // wrong check digit
assert!(!is_valid("07291716092")); // must not start with 0

assert_eq!(validate(" 17291716060 ").unwrap(), "17291716060"); // trims whitespace
assert_eq!(calc_check_digits("172917160").unwrap(), "60");      // the two check digits

The number is valid when it has 11 digits, does not start with 0, and its last two digits equal check1 = (10 - Σ wᵢ·dᵢ) mod 10 and check2 = (check1 + Σ dᵢ) mod 10 computed over the first nine digits (weights 3,1,3,1,…).
