Struct LanguageRequesterImpl 

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

Provide the functionality for overrides and listeners for a LanguageRequester implementation.

Implementations

impl<'a> LanguageRequesterImpl<'a>

pub fn new() -> LanguageRequesterImpl<'a>

Create a new LanguageRequesterImpl.

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

Set an override for the requested language which is used when the LanguageRequesterImpl#poll() method is called. If None, then no override is used.

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

Add a weak reference to a Localizer, which listens to changes to the current language.

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

Add a reference to Localizer, which listens to changes to the current language.

pub fn poll_without_override( &mut self, requested_languages: Vec<LanguageIdentifier>, ) -> Result<(), I18nEmbedError>

With the provided requested_languages call Localizer#select() on each of the listeners.

pub fn poll( &mut self, requested_languages: Vec<LanguageIdentifier>, ) -> Result<(), I18nEmbedError>

With the provided requested_languages call Localizer#select() on each of the listeners. The requested_languages may be ignored if #set_language_override() has been set.

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

The languages reported to be available in the listener Localizers.

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

Gets a HashMap with what each language is currently set (value) per domain (key).
