Struct icu_provider::hello_world::HelloWorldProvider

pub struct HelloWorldProvider { /* private fields */ }

A data provider returning Hello World strings in different languages.

Mostly useful for testing.

Examples

use icu_provider::hello_world::*;
use icu_provider::prelude::*;
use icu_locid::locale;

let provider = HelloWorldProvider::new_with_placeholder_data();

let german_hello_world: DataPayload<HelloWorldV1Marker> = provider
    .load_resource(&DataRequest {
        options: locale!("de").into(),
        metadata: Default::default(),
    })
    .expect("Loading should succeed")
    .take_payload()
    .expect("Data should be present");

assert_eq!("Hallo Welt", german_hello_world.get().message);
