Performs a Luhn algorithm check on given number, returns true/false.
It is luhn2
because there already is a luhn package but poorly
documented and with almost no tests (looks like first rust try).
Add this to your Cargo.toml
:
[dependencies]
luhn2 = "0.1"
and this to your crate root:
extern crate luhn2;
use luhn2::validate;
