Struct icu_capi::provider::ffi::DataProvider

pub struct DataProvider(pub DataProviderInner);

An ICU4X data provider, capable of loading ICU4X data keys from some source.

Currently the only source supported is loading from “blob” formatted data from a bytes buffer or the file system.

If you wish to use ICU4X’s builtin “compiled data”, use the version of the constructors that do not have _with_provider in their names.

Implementations

impl DataProvider

pub fn from_fs(path: &DiplomatStr) -> Result<Box<DataProvider>, DataError>

Constructs an FsDataProvider and returns it as an DataProvider. Requires the provider_fs Cargo feature. Not supported in WASM.

pub fn from_byte_slice( blob: &'static [DiplomatByte], ) -> Result<Box<DataProvider>, DataError>

Constructs a BlobDataProvider and returns it as an DataProvider.

pub fn fork_by_key(&mut self, other: &mut DataProvider) -> Result<(), DataError>

Creates a provider that tries the current provider and then, if the current provider doesn’t support the data key, another provider other.

This takes ownership of the other provider, leaving an empty provider in its place.

The providers must be the same type (Any or Buffer). This condition is satisfied if both providers originate from the same constructor, such as create_from_byte_slice or create_fs. If the condition is not upheld, a runtime error occurs.

pub fn fork_by_locale( &mut self, other: &mut DataProvider, ) -> Result<(), DataError>

Same as fork_by_key but forks by locale instead of key.

pub fn enable_locale_fallback_with( &mut self, fallbacker: &LocaleFallbacker, ) -> Result<(), DataError>
