Struct icu_provider::struct_provider::StructProvider

pub struct StructProvider<'data, M> where
    M: DataMarker<'data>,  {
    pub key: ResourceKey,
    pub data: DataPayload<'data, M>,
}

A data provider that returns clones of a constant data payload.

Examples

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

let local_data = HelloWorldV1 {
    message: Cow::Owned("hello world".to_string()),
};

// A placeholder key to use to serve the data struct
const SAMPLE_KEY: ResourceKey = icu_provider::resource_key!(x, "xyz", "example", 1);

let provider = StructProvider {
    key: SAMPLE_KEY,
    data: DataPayload::from_owned(local_data),
};

let payload: DataPayload<HelloWorldV1Marker> = provider.load_payload(&DataRequest::from(SAMPLE_KEY))
    .expect("Load should succeed")
    .take_payload()
    .expect("Data should be present");

assert_eq!(payload.get().message, "hello world");

Fields

key: ResourceKey

data: DataPayload<'data, M>
