Parsing, manipulating, and serializing Unicode Language and Locale Identifiers.
This module is published as its own crate (icu_locid)
and as part of the icu crate. See the latter for more details on the ICU4X project.
The module provides algorithms for parsing a string into a well-formed language or locale identifier
as defined by [UTS #35: Unicode LDML 3. Unicode Language and Locale Identifiers].
[Locale] is the most common structure to use for storing information about a language,
script, region, variants and extensions. In almost all cases, this struct should be used as the
base unit for all locale management operations.
[LanguageIdentifier] is a strict subset of [Locale] which can be useful in a narrow range of
cases where [Unicode Extensions] are not relevant.
If in doubt, use [Locale].
```rust use icu::locid::Locale; use icu::locid::{ locale, subtagslanguage as language, subtagsregion as region, };
let mut loc: Locale = locale!("en-US");
asserteq!(loc.id.language, language!("en")); asserteq!(loc.id.script, None); asserteq!(loc.id.region, Some(region!("US"))); asserteq!(loc.id.variants.len(), 0);
loc.id.region = Some(region!("GB"));
assert_eq!(loc, locale!("en-GB")); ```
