This crate implements the ISO 639-1 standard in Rust.
It also has optional Serde support, by using the serde feature:
isolanguage-1 = { version = "0.2.2", features = ["serde"] }The main type is the LanguageCode type, which is an enum for every single language in ISO
639-1. It optionally implements Serialize and Deserialize too.
