isin

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:

• 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)

Usage

Add this to your Cargo.toml:

toml [dependencies] isin = "0.1"

Example

rust 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), }
