OxiLangTag is a Rust library allowing to validate and normalize language tags following RFC 5646 (BCP 47).
It is a fork of the language-tags focusing on RDF use cases.
You might find the language-tags crate more convenient.
It allows zero stack allocation language tag validation. Getters are also provided to easily retrieve the various language tag components.
If serde is available, LanguageTag implements the Serialize and Deserialize traits and encodes the language tag as a string.
Example:
use oxilangtag::LanguageTag;
// Parsing and validation
let language_tag = LanguageTag::parse("zh-cmn-Hans-CN-x-test").unwrap();
assert_eq!(language_tag.as_str(), "zh-cmn-Hans-CN-x-test");
// Language tag components
assert_eq!(language_tag.primary_language(), "zh");
assert_eq!(language_tag.extended_language(), Some("cmn"));
assert_eq!(language_tag.full_language(), "zh-cmn");
assert_eq!(language_tag.script(), Some("Hans"));
assert_eq!(language_tag.region(), Some("CN"));
assert_eq!(language_tag.extension(), None);
assert_eq!(language_tag.private_use_subtags().collect::<Vec<_>>(), vec!["test"]);This project is licensed under the MIT license (LICENSE-MIT or <http://opensource.org/licenses/MIT>).
