ISO 639 language codes
When dealing with different language inputs and APIs, different standards are used to identify a language. Converting between these in an automated way can be tedious. This crate provides an enum which supports conversion from 639-1 and 639-3 and also into these formats, as well as into English names or autonyms (local names).
This crate contains the ISO 639 table in statically embedded tables. This increases binary size, but allows for very efficient look-up if performance matters. If size is a concern, both and the English names and local names can be enabled or disabled individually.

[dependencies] isolang = "2.0"
use isolang::Language; assert_eq!(Language::from_639_1("de").unwrap().to_name(), "German"); assert_eq!(Language::from_639_3("spa").unwrap().to_639_1(), Some("es")); // undefined language (ISO code und) assert_eq!(Language::default(), Language::Und);
This crate also supports serializing the
Language enum. To enable this please
add the following lines to your
Cargo.toml (instead of the above code):
