Struct icu_provider_fs::FsDataProvider

pub struct FsDataProvider { /* private fields */ }

A data provider that reads ICU4X data from a filesystem directory.

FsDataProvider implements BufferProvider, so it can be used in *_with_buffer_provider constructors across ICU4X.

Examples

use icu_locid::locale;
use icu_provider::hello_world::HelloWorldFormatter;
use icu_provider_fs::FsDataProvider;
use writeable::assert_writeable_eq;

// Create a DataProvider from data files stored in a filesystem directory:
let provider = FsDataProvider::try_new(concat!(
    env!("CARGO_MANIFEST_DIR"),
    "/tests/data/json",
))
.expect("Directory exists");

// Check that it works:
let formatter = HelloWorldFormatter::try_new_with_buffer_provider(
    &provider,
    &locale!("la").into(),
)
.expect("locale exists");

assert_writeable_eq!(formatter.format(), "Ave, munde");

Implementations

impl FsDataProvider

pub fn try_new<T: Into<PathBuf>>(root: T) -> Result<Self, DataError>

Create a new FsDataProvider given a filesystem directory.

Examples

use icu_provider_fs::FsDataProvider;

let provider = FsDataProvider::try_new("/path/to/data/directory")
    .expect_err("Specify a real directory in the line above");
