Crate icu_provider_export

icu_provider_export is a library to generate data files that can be used in ICU4X data providers.

For command-line usage, see the icu4x-datagen binary.

Also see our datagen tutorial.

Examples

use icu_provider_export::blob_exporter::*;
use icu_provider_export::prelude::*;
use icu_provider_source::SourceDataProvider;
use std::fs::File;

let provider = SourceDataProvider::new();

ExportDriver::new(
    [DataLocaleFamily::FULL],
    DeduplicationStrategy::None.into(),
    LocaleFallbacker::try_new_unstable(&provider).unwrap(),
)
.with_markers([icu::list::provider::ListAndV1::INFO])
.export(
    &provider,
    BlobExporter::new_with_sink(Box::new(
        File::create("data.postcard").unwrap(),
    )),
)
.unwrap();
