lib.rs Canonicalization of locale identifiers based on [`CLDR`] data. This module is published as its own crate ([`icu_locid_transform`](https://docs.rs/icu_locid_transform/latest/icu_locid_transform/)) and as part of the [`icu`](https://docs.rs/icu/latest/icu/) crate. See the latter for more details on the ICU4X project. It currently supports locale canonicalization based upon the canonicalization algorithm from [`UTS #35: Unicode LDML 3. LocaleId Canonicalization`], as well as the minimize and maximize likely subtags algorithms as described in [`UTS #35: Unicode LDML 3. Likely Subtags`]. The maximize method potentially updates a passed in locale in place depending up the results of running the 'Add Likely Subtags' algorithm from [`UTS #35: Unicode LDML 3. Likely Subtags`]. This minimize method returns a new Locale that is the result of running the 'Remove Likely Subtags' algorithm from [`UTS #35: Unicode LDML 3. Likely Subtags`]. # Examples ``` use icu::locid::Locale; use icu::locid_transform::{LocaleCanonicalizer, TransformResult}; let lc = LocaleCanonicalizer::new(); let mut locale: Locale = "ja-Latn-fonipa-hepburn-heploc" .parse() .expect("parse failed"); assert_eq!(lc.canonicalize(&mut locale), TransformResult::Modified); assert_eq!(locale, "ja-Latn-alalc97-fonipa".parse::<Locale>().unwrap()); ``` ``` use icu::locid::locale; use icu::locid_transform::{LocaleExpander, TransformResult}; let lc = LocaleExpander::new(); let mut locale = locale!("zh-CN"); assert_eq!(lc.maximize(&mut locale), TransformResult::Modified); assert_eq!(locale, locale!("zh-Hans-CN")); let mut locale = locale!("zh-Hant-TW"); assert_eq!(lc.maximize(&mut locale), TransformResult::Unmodified); assert_eq!(locale, locale!("zh-Hant-TW")); ``` ``` use icu::locid::locale; use icu::locid_transform::{LocaleExpander, TransformResult}; use writeable::assert_writeable_eq; let lc = LocaleExpander::new(); let mut locale = locale!("zh-Hans-CN"); assert_eq!(lc.minimize(&mut locale), TransformResult::Modified); assert_eq!(locale, locale!("zh")); let mut locale = locale!("zh"); assert_eq!(lc.minimize(&mut locale), TransformResult::Unmodified); assert_eq!(locale, locale!("zh")); ``` [`ICU4X`]: ../icu/index.html [`CLDR`]: http://cldr.unicode.org/ [`UTS #35: Unicode LDML 3.
