isin
====
An `ISIN` type for working with validated International Security Identifiers (ISINs) as defined in
[ISO 6166](https://www.iso.org/standard/78502.html).

The checksum calculation uses a table-driven algorithm to minimize overhead _vs._ a direct translation of the formula
definition.
 

## Usage

Add this to your `Cargo.toml`:

```toml
[dependencies]
isin = "0.1"
```


## Example

```rust
use isin::ISIN;
let isin_string = "US0378331005";
match ISIN::parse_strict(isin_string) {
    Ok(isin) => {
        println!("Parsed ISIN: {}", isin.value()); // "US0378331005"
        println!("  Country code: {}", isin.country_code()); // "US"
        println!("  Security identifier: {}", isin.security_identifier()); // "037833100"
        println!("  Check digit: {}", isin.check_digit()); // "5"
    }
    Err(err_string) => panic!("Unable to parse ISIN {}: {}", isin_string, err_string),
}
```
