For more details, see [`LanguageIdentifier`]. +//! +//! # Optional features +//! +//! ## `langid!` and `langids!` macros +//! +//! If `feature = "macros"` is selected, the crate provides a procedural macro +//! which allows to construct build-time well-formed language identifiers with zero-cost at runtime. +//! +//! ``` ignore +//! use unic_langid::{langid, langids, lang, region, script, variant}; +//! use unic_langid::subtags::{Language, Script, Region, Variant}; +//! use std::str::FromStr; +//! +//! let es_ar = langid!("es-AR"); +//! let en_us = langid!("en-US"); +//! +//! assert_eq!(&es_ar.to_string(), "es-AR"); +//! assert_eq!(&en_us.to_string(), "en-US"); +//! +//! let lang_ids = langids!("es-AR", "en-US", "de"); +//! +//! assert_eq!(lang_ids[0], "es-AR"); +//! assert_eq!(lang_ids[1], "en-US"); +//! assert_eq!(lang_ids[2], "de"); +//! +//! assert_eq!(lang!("pl"), "pl"); +//! assert_eq!(lang!("pl"), Language::from_str("pl").unwrap()); +//! +//! assert_eq!(script!("latn"), "Latn"); +//! assert_eq!(script!("latn"), Script::from_str("Latn").unwrap()); +//! +//! assert_eq!(region!("us"), "US"); +//! assert_eq!(region!("us"), Region::from_str("us").unwrap()); +//! +//! assert_eq!(variant!("macos"), "macos"); +//! assert_eq!(variant!("macos"), Variant::from_str("macos").unwrap()); +//! ``` +//! +//! The macros produce instances of `LanguageIdentifier` the same way as parsing from `&str` does, +//! but since the parsing is performed at build time, it doesn't need a `Result`. +//! +//! At the moment `langid!` can also be used for const variables, but only if no variants are used. +//! +//! The macros are optional to reduce the dependency chain and compilation time of `unic-langid`. +//! +//! ## Likely Subtags +//! +//! If `feature = "likelysubtags"` is selected, the `LanguageIdentifier` gains two more methods: +//! +//! * add_likely_subtags +//! * remove_likely_subtags +//! +//! Both of them operate in place updating the existing `LanguageIdentifier` by either extending +//! subtags to most likely values, or removing the subtags that are not needed. +//! +//! Both methods return a `bool` that indicates if the identifier has been modified. +//! +//! ``` ignore +//! use unic_langid::LanuageIdentifier; +//! +//! let mut li: LanguageIdentifier = "fr-FR".parse() +//! .expect("Parsing failed."); +//! +//! assert_eq!(li.add_likely_subtags(), true); +//! assert_eq!(li, "fr-Latn-FR"); +//! +//! assert_eq!(li.remove_likely_subtags(), true); +//! assert_eq!(li, "fr"); +//! ``` +//! +//! The feature is optional because it increases the binary size of the library by including +//! a data table for CLDR likelySubtags. +//! +//!
