trid - Turkish Citizenship ID Number crate

This is my first ever written Rust code derived from my own TurkishId package for .NET. I'm trying to use existing code as an excuse to learn about Rust. Despite constant tackling with error messages, Rust has been extremely impressive so far. (How cool are doc-tests!?)

Usage

parse

The crate provides TurkishId type that represents a valid Turkish ID number. It can be instantiated from a string using the parse() method of str type. TurkishId type guarantess that it never contains an invalid Turkish ID number, so there's no need to validate a TurkishId once parsed. It can always be passed around safely.

is_valid

You can just verify whether a string contains a valid Turkish ID or not by calling is_valid(value: &str) function.

from_seq

If you want to generate a Turkish ID from scratch, you can use from_seq(seq: u32) function.

Internals

The type occupies 11 bytes in memory and kept as ASCII representation of the number in order to make string display conversions fast. The other alternative would be to have it in a 40-bit number which would complicate the string representation.

Examples

Validate a Turkish citizenship ID number:

fn main() {
    if trid::is_valid("12345678901") {
        // yayyy!
    }
}

Try parsing a string into TurkishId:

use trid::TurkishId;

fn main() {
    let id : TurkishId = "12345678901".parse()?;
}

Generate infinite number of random but valid Turkish IDs:

use rand::Rng;
use trid::TurkishId;

fn main() {
    let mut rng = rand::thread_rng();
    loop {
        let seq: u32 = rng.gen_range(100_000_000..1_000_000_000);
        println!("{}", TurkishId::from_seq(seq).unwrap());
    }
}
