upc-checker

Overview

About

upc-checker is a small Rust Crate for quickly checking a UPC code compared to a check digit. Some more of the in-depth of this process can be found here. This is my first Rust Crate so apologies if it isn't memory efficiant as it could be (though it uses only i8, i8 and u16 for data ints).

An Example

Here is a small example of upc-checker in action:

extern crate upc_checker;

fn main() {
    let my_code: Vec<i8> = vec![0, 3, 6, 0, 0, 0, 2, 4, 1, 4, 5]; // This is the main UPC code
    let my_check_digit: i8 = 7; // This is the UPC check digit

    let my_upc_code_struct = UPCCode { // Creating a structure with the UPC components inside
        code: my_code,
        check_digit: my_check_digit,
    };

    match my_upc_code_struct.check_code() { // `my_upc_code_struct.check_code()` returns `Result<bool, std::io::Error>`.
        Ok(x) => (), // `x` is a bool
        Err(_) => (), // Deal as you like
    }
}
