Struct Localization 

pub struct Localization(/* private fields */);

Shared application localization used by UI roots, workers, and native services. Each thread retains only its most recently used formatter. Language changes invalidate that formatter; repeated messages do not reconstruct Fluent bundles.

Implementations

impl Localization

pub fn new(catalog: Catalog, system: Vec<Locale>) -> Self

Creates an application scope with automatic system-language selection.

pub fn persistent( catalog: Catalog, system: Vec<Locale>, store: impl LanguagePreferenceStore + 'static, ) -> Self

Creates an application scope backed by its own preference storage.

pub fn catalog(&self) -> &Catalog

The application’s catalog and supported language choices.

pub fn is_persistent(&self) -> bool

Whether preference changes access application storage. Without storage, selection is immediate and needs no worker runtime.

pub fn preference(&self) -> LanguagePreference

The current saved or explicitly selected preference.

pub fn revision(&self) -> u64

A version that changes when the selected preference or host languages change.

pub fn load(&self) -> Result<(), LocalizationError>

Loads stored preferences without replacing a newer user selection. This can access storage; native applications should call it on a worker.

pub fn select( &self, preference: LanguagePreference, ) -> Result<(), LocalizationError>

Persists a choice and publishes it only after storage succeeds. Calls are serialized; native applications should call this on a worker.

pub fn refresh_system(&self, system: &[Locale]) -> bool

Updates the ordered host preferences without changing an explicit choice.

pub fn translator(&self) -> Translator

Creates a formatter for the current application choice on this thread.

pub fn format( &self, message: &DeferredMessage, ) -> Result<String, LocalizationError>

Resolves a deferred message on any thread using its cached formatter.

pub fn text(&self, message: &DeferredMessage) -> String

Resolves native UI text, with readable source text if a runtime resource is malformed.
