Crate langtag

source ·
Expand description

This crate provides an implementation of language tags defined by RFC5646 (BCP47).

§Usage

You can easily parse new language from any string:

use langtag::LangTag;

fn main() -> Result<(), langtag::InvalidLangTag<&'static str>> {
  let tag = LangTag::new("fr-FR")?;
  assert_eq!(tag.language().unwrap().primary(), "fr");
  assert!(tag == "Fr-fr"); // comparison is case-insensitive.
  Ok(())
}

Note that LangTag::new does not copy the data it is given, but only borrows it. The LangTagBuf type allows you to own the language tag. Once parsed, you can explore every component of the language tag using the provided functions.
