An object-safe data provider that returns data structs cast to dyn Any trait objects.

Examples

use icu_provider::hello_world::*;
use icu_provider::prelude::*;
use std::borrow::Cow;

let any_response = HelloWorldProvider
    .as_any_provider()
    .load_any(
        HelloWorldV1Marker::KEY,
        DataRequest {
            locale: &icu_locid::locale!("de").into(),
            metadata: Default::default(),
        },
    )
    .expect("Load should succeed");

// Downcast to something useful
let response: DataResponse<HelloWorldV1Marker> =
    any_response.downcast().expect("Types match");

let payload = response.take_payload().expect("Data should be present");

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