Struct icu_provider::hello_world::HelloWorldProvider

pub struct HelloWorldProvider;

A data provider returning Hello World strings in different languages.

Mostly useful for testing.

Examples

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

let german_hello_world: DataPayload<HelloWorldV1Marker> =
    HelloWorldProvider
        .load(DataRequest {
            locale: &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);
