icu_locale
Canonicalization of locale identifiers based on CLDR
data.
This module is published as its own crate (icu_locale
)
and as part of the 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::locale::Locale;
use icu::locale::{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::locale::{locale, LocaleExpander, TransformResult};
let lc = LocaleExpander::new();
let mut locale = locale!("zh-CN");
assert_eq!(lc.maximize(&mut locale.id), TransformResult::Modified);
assert_eq!(locale, locale!("zh-Hans-CN"));
let mut locale = locale!("zh-Hant-TW");
assert_eq!(lc.maximize(&mut locale.id), TransformResult::Unmodified);
assert_eq!(locale, locale!("zh-Hant-TW"));
use icu::locale::{locale, LocaleExpander, TransformResult};
use writeable::assert_writeable_eq;
let lc = LocaleExpander::new();
let mut locale = locale!("zh-Hans-CN");
assert_eq!(lc.minimize(&mut locale.id), TransformResult::Modified);
assert_eq!(locale, locale!("zh"));
let mut locale = locale!("zh");
assert_eq!(lc.minimize(&mut locale.id), TransformResult::Unmodified);
assert_eq!(locale, locale!("zh"));
