Struct HelloWorldProvider

pub struct HelloWorldProvider;

A data provider returning Hello World strings in different languages.

Mostly useful for testing.

Examples

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

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

Load the reverse string using an auxiliary key:

use icu_provider::hello_world::*;
use icu_provider::prelude::*;

let reverse_hello_world: DataPayload<HelloWorldV1Marker> =
    HelloWorldProvider
        .load(DataRequest {
            locale: &"en-x-reverse".parse().unwrap(),
            metadata: Default::default(),
        })
        .expect("Loading should succeed")
        .take_payload()
        .expect("Data should be present");

assert_eq!("Olleh Dlrow", reverse_hello_world.get().message);

Trait Implementations

impl DataProvider<HelloWorldV1Marker> for HelloWorldProvider

fn load( &self, req: DataRequest<'_>, ) -> Result<DataResponse<HelloWorldV1Marker>, DataError>

Query the provider for data, returning the result.

impl Debug for HelloWorldProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HelloWorldProvider

fn default() -> HelloWorldProvider

Returns the “default value” for a type.

impl DynamicDataProvider<AnyMarker> for HelloWorldProvider

fn load_data( &self, key: DataKey, req: DataRequest<'_>, ) -> Result<DataResponse<AnyMarker>, DataError>

Query the provider for data, returning the result.

impl PartialEq for HelloWorldProvider

fn eq(&self, other: &HelloWorldProvider) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
