HETU validator and generator in Rust

Simple crate for validating and generating Finnish Personal Identity Code (HETU).

Works with rust 1.8 stable.

Usage

Add this to your Cargo.toml

[dependencies.hetu]
git = "https://github.com/jelovirt/hetu.git"

To validate:

extern crate hetu;
use hetu::Ssn;

pub fn main() {
  if Ssn::parse("121212-121D").is_ok() {
    println!("Valid HETU")
  } else {
    println!("Invalid")
  }
}

To generate:

extern crate hetu;
use hetu::Ssn;

pub fn main() {
  println!("{}", Ssn::generate());
}

To generate by pattern:

extern crate hetu;
use hetu::Ssn;
use hetu::SsnPattern;

pub fn main() {
  let pattern = SsnPattern::parse("111111-111?").unwrap();
  println!("{}", Ssn::generate_by_pattern(pattern).unwrap());
}

CLI

Command line tool hetu can be used to either validate or randomly generate identifiers.

To validate:

$ hetu 121212-121D
$ echo 121212-121D | hetu -
$ hetu 121212-121C
Error: Invalid checksum: expected D
  
  121212-121C
            ^

To generate:

$ hetu
121212-121D

To generate by pattern that can contain wildcards:

$ hetu -p "121212-121?"
121212-121D
$ hetu -p "121212-???D"
121212-028D
$ hetu -p "??????-???D"
