Implementations

impl ICU4XDataProvider

pub fn create_compiled() -> Box<ICU4XDataProvider>

Constructs an ICU4XDataProvider that uses compiled data.

Requires the compiled_data feature.

This provider cannot be modified or combined with other providers, so enable_fallback, enabled_fallback_with, fork_by_locale, and fork_by_key will return Errs.

pub fn create_empty() -> Box<ICU4XDataProvider>

Constructs an empty ICU4XDataProvider.

pub fn fork_by_key( &mut self, other: &mut ICU4XDataProvider, ) -> Result<(), ICU4XError>

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 ICU4XDataProvider, ) -> Result<(), ICU4XError>

Same as fork_by_key but forks by locale instead of key.

pub fn enable_locale_fallback(&mut self) -> Result<(), ICU4XError>

Enables locale fallbacking for data requests made to this provider.

Note that the test provider (from create_test) already has fallbacking enabled.
