Package codes-iso-4217

This package contains an implementation of the ISO 4217 Currency Codes specification.

This standard establishes internationally recognized codes for the representation of currencies that enable clarity and reduce errors. Currencies are represented both numerically and alphabetically, using either three digits or three letters. Some of the alphabetic codes for major currencies are familiar, such as "EUR" for Euros. Fortunately, ISO 4217 covers everything from Afghanis to Zambian Kwacha as well.

This package extends the data model of the ISO specification by adding a currency symbol string (and Unicode code points for the symbol) where possible to all symbols.

For notes on the design of the API, see the repository README.

Example

use codes_iso_4217::{CurrencyCode, ISO_4217};

let code = CurrencyCode::BZD;

assert_eq!(code.alpha_code(), "BZD");
assert_eq!(code.numeric_code(), Some(84));

// feature = "currency_name"
assert_eq!(code.currency_name(), "Belize Dollar");

// feature = "country_name"
assert_eq!(code.country_name(), "BELIZE");

// feature = "monetary_units"
assert_eq!(code.monetary_units(), 2);

// feature = "is_fund"
assert_eq!(code.is_fund(), false);

// feature = "historical_codes"
assert_eq!(code.is_historical(), false);
assert_eq!(code.withdrawal_date(), None);

// feature = "symbols"
assert_eq!(code.currency_symbol_str(), Some("BZ$"));
assert_eq!(code.currency_symbol_code_points(), Some(&[0x42, 0x5a, 0x24]));

assert_eq!(ISO_4217.title(), "Currency codes");

Features

By default only the serde feature is enabled, the CurrencyCode::alpha_code and CurrencyCode::numeric_code methods cannot be excluded.

• serde - Enables serialization of the CurrencyCode type.
• currency_name - Adds the CurrencyCode::currency_name method.
• country_name - Adds the CurrencyCode::country_name method.
• monetary_units - Adds the CurrencyCode::monetary_units method.
• is_fund - Adds the CurrencyCode::is_fund method.
• historical_codes - Adds the CurrencyCode::is_historical and CurrencyCode::withdrawal_date methods.
• symbols - Adds the CurrencyCode::currency_symbol_str and CurrencyCode::currency_symbol_code_points methods.

Changes

Version 0.1.7

• Catering for new build module in codes-common

Version 0.1.6

• Implemented Standardized and FixedLengthCode traits.

Version 0.1.5

• Added symbols, scraped from xe.com
• Synced the examples, with commented out lines for feature-gated methods.

Version 0.1.4

• Added ALL_CODES constant.

Version 0.1.3

• Clean-up implementation based on newer codes-common
• Using new Code trait and macro-created implementation.

Version 0.1.2

• Added more documentation.
• Removed the implementation of the Code trait.
• Changed error type to enum from struct.

Version 0.1.1

• Completed the build-time work to generate the CurrencyCode type and methods. Took heavy inspiration from penny but wanted a different resulting style.

Version 0.1.0

• Initial place-holder release.

TODO

1. Create a scheduled build that retrieves updated files from the ISO site.
