Function use_init_i18n 

pub fn use_init_i18n(init: impl FnOnce() -> I18nConfig) -> I18n

Initialize an I18n instance and provide it to descendant components.

This is the recommended way to set up i18n in your application. Call it once in a root component and then use I18n::get (or the t!, te!, tid! macros) in any descendant component to access translations.

See I18n::create for a manual initialization where you can also handle errors.

Panics

Panics if the I18nConfig fails to produce a valid Fluent bundle.

fn app() -> impl IntoElement {
    let mut i18n = use_init_i18n(|| {
        I18nConfig::new(langid!("en-US"))
            .with_locale(Locale::new_static(
                langid!("en-US"),
                include_str!("../../../examples/i18n/en-US.ftl"),
            ))
            .with_locale(Locale::new_dynamic(
                langid!("es-ES"),
                "../../../examples/i18n/es-ES.ftl",
            ))
    });

    let change_to_spanish = move |_| i18n.set_language(langid!("es-ES"));

    rect()
        .child(t!("hello_world"))
        .child(Button::new().on_press(change_to_spanish).child("Spanish"))
}
