Implementations

impl WebLanguageRequester<'_>

pub fn new() -> Self

Create a new WebLanguageRequester.

pub fn requested_languages() -> Vec<LanguageIdentifier>

The languages currently being requested by the browser context.

Trait Implementations

impl<'a> Debug for WebLanguageRequester<'a>

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

Formats the value using the given formatter.

impl Default for WebLanguageRequester<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> LanguageRequester<'a> for WebLanguageRequester<'a>

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

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

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 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().
