Struct icu_locid_transform::LocaleCanonicalizer

source ·
pub struct LocaleCanonicalizer { /* private fields */ }
Expand description

Implements the algorithm defined in UTS #35: Annex C, LocaleId Canonicalization.

§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().unwrap();
assert_eq!(lc.canonicalize(&mut locale), TransformResult::Modified);
assert_eq!(locale, "ja-Latn-alalc97-fonipa".parse().unwrap());

pub fn canonicalize(&self, locale: &mut Locale) -> TransformResult

The canonicalize method potentially updates a passed in locale in place depending up the results of running the canonicalization algorithm from http://unicode.org/reports/tr35/#LocaleId_Canonicalization.

Some BCP47 canonicalization data is not part of the CLDR json package. Because of this, some canonicalizations are not performed, e.g. the canonicalization of und-u-ca-islamicc to und-u-ca-islamic-civil. This will be fixed in a future release once the missing data has been added to the CLDR json data. See: https://github.com/unicode-org/icu4x/issues/746

§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().unwrap();
assert_eq!(lc.canonicalize(&mut locale), TransformResult::Modified);
assert_eq!(locale, "ja-Latn-alalc97-fonipa".parse().unwrap());
