Struct DesktopLanguageRequester 

pub struct DesktopLanguageRequester<'a> { /* private fields */ }

A LanguageRequester for the desktop platform, supporting windows, linux and mac. It uses sys-locale to select the language based on the system selected language.

⚠️ This API requires the following crate features to be activated: desktop-requester.

Implementations

impl DesktopLanguageRequester<'_>

pub fn new() -> Self

Create a new DesktopLanguageRequester.

pub fn requested_languages() -> Vec<LanguageIdentifier>

The languages being requested by the operating system/environment according to the [sys-locale] crate’s implementation.

Trait Implementations

impl<'a> Debug for DesktopLanguageRequester<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DesktopLanguageRequester<'_>

Available on crate feature desktop-requester only.

fn default() -> Self

Returns the “default value” for a type.

impl<'a> LanguageRequester<'a> for DesktopLanguageRequester<'a>

Available on crate feature desktop-requester only.

fn requested_languages(&self) -> Vec<LanguageIdentifier>

The currently requested languages.

fn add_listener(&mut self, listener: Weak<dyn Localizer>)

Add a listener to this LanguageRequester. When the system reports that the currently requested languages has changed, each listener will have its Localizer#select() method called. Weak is used so that when the Arc that it references is dropped, the listener will also be removed next time this requester is polled/updates.

fn add_listener_ref(&mut self, listener: &'a dyn Localizer)

Add a listener to this LanguageRequester. When the system reports that the currently requested languages has changed, each listener will have its Localizer#select() method called. As opposed to LanguageRequester::add_listener(), this listener will not be removed.

fn set_language_override( &mut self, language_override: Option<LanguageIdentifier>, ) -> Result<(), I18nEmbedError>

Override the languages fed to the Localizer listeners during a #poll(). Set this as None to disable the override.

fn poll(&mut self) -> Result<(), I18nEmbedError>

Poll the system’s currently selected language, and call Localizer#select() on each of the listeners.

fn available_languages(&self) -> Result<Vec<LanguageIdentifier>, I18nEmbedError>

The languages reported to be available in the listener Localizers.

fn current_languages(&self) -> HashMap<String, LanguageIdentifier>

The languages currently loaded, keyed by the LanguageLoader::domain().
