Crate icu_testdata

👎Deprecated since 1.3.0: this crate has been superseded by ICU4X’s compiled_data feature. Data for new components will not be added, and it will not be updated for ICU4X 2.0.

icu_testdata is a unit testing crate for ICU4X.

The crate exposes data providers with stable data useful for unit testing. The data is based on a CLDR tag and a short list of locales that, together, cover a range of scenarios.

The crate exposes three kinds of providers, corresponding to the three types of constructors in ICU:

• unstable, unstable_no_fallback
• any, any_no_fallback
• buffer, buffer_no_fallback (buffer Cargo feature)

Examples

use icu::locid::locale;
use icu_provider::hello_world::HelloWorldFormatter;

// Unstable constructor
HelloWorldFormatter::try_new_unstable(
    &icu_testdata::unstable(),
    &locale!("en-CH").into(),
).unwrap();

// AnyProvider constructor
HelloWorldFormatter::try_new_with_any_provider(
    &icu_testdata::any(),
    &locale!("en-CH").into(),
).unwrap();

// BufferProvider constructor (`icu` with `serde` feature, `icu_testdata` with `buffer` feature)
HelloWorldFormatter::try_new_with_buffer_provider(
    &icu_testdata::buffer(),
    &locale!("en-CH").into(),
).unwrap();

// Without fallback the locale match needs to be exact
HelloWorldFormatter::try_new_unstable(
    &icu_testdata::unstable_no_fallback(),
    &locale!("en-CH").into(),
).is_err();

HelloWorldFormatter::try_new_unstable(
    &icu_testdata::unstable_no_fallback(),
    &locale!("en").into(),
).unwrap();

versionsDeprecated

Functions to access version info of the ICU test data.

Functions

bufferDeprecated

A BufferProvider backed by a Postcard blob.

buffer_no_fallbackDeprecated

A BufferProvider backed by a Postcard blob.
