icu_locid

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].

Examples

```rust use icu::locid::Locale; use icu::locid::{ locale, subtags::{language, 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")); ```

For more details, see [Locale] and [LanguageIdentifier].
