Countries list from ISO 3166-1

Usage

After cargo install countries-tools:

use countries_tools::{Country, CountryAlpha2};

assert_eq!(Country::from(CountryAlpha2::ES).short_name(), "Spain");

use countries_tools::{Country, CountryAlpha3};

assert_eq!(Country::from(CountryAlpha3::USA).short_name(), "United States of America");

use countries_tools::Country;

assert_eq!(Country::try_from(392).unwrap().short_name(), "Japan");

As much methods as possible are const fn to allow compile-time computation and optimize runtime performance.

Also this crate is no_std compatible. The crate size is kept as small as possible and also the impact on the binary size.
