An ISIN type for working with validated International Security Identifiers (ISINs) as defined in ISO 6166.

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

This crate is part of the Financial Identifiers series:

• CIK: Central Index Key (SEC EDGAR)
• CUSIP: Committee on Uniform Security Identification Procedures (ANSI X9.6-2020)
• ISIN: International Securities Identification Number (ISO 6166:2021)
• LEI: Legal Entity Identifier (ISO 17442:2020)

Add this to your Cargo.toml:

[dependencies]
isin = "0.1"

use isin;
let isin_string = "US0378331005";
match isin::parse(isin_string) {
    Ok(isin) => {
        println!("Parsed ISIN: {}", isin.to_string()); // "US0378331005"
        println!("  Prefix: {}", isin.prefix()); // "US"
        println!("  Basic code: {}", isin.basic_code()); // "037833100"
        println!("  Check digit: {}", isin.check_digit()); // '5'
    }
    Err(err) => panic!("Unable to parse ISIN {}: {}", isin_string, err),
}
