Detailed Description

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

See the Rust documentation for icu_provider for more information.

Member Function Documentation

create_compiled()

ICU4XDataProvider ICU4XDataProvider::create_compiled ( )

inlinestatic

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.

create_empty()

ICU4XDataProvider ICU4XDataProvider::create_empty ( )

inlinestatic

Constructs an empty [ICU4XDataProvider].

See the Rust documentation for EmptyDataProvider for more information.

create_from_byte_slice()

diplomat::result< ICU4XDataProvider, ICU4XError > ICU4XDataProvider::create_from_byte_slice ( const diplomat::span< const uint8_t > blob )

inlinestatic

Constructs a BlobDataProvider and returns it as an [ICU4XDataProvider].

See the Rust documentation for BlobDataProvider for more information.

Lifetimes: blob must live for the duration of the program.

create_fs()

diplomat::result< ICU4XDataProvider, ICU4XError > ICU4XDataProvider::create_fs ( const std::string_view path )

inlinestatic

Constructs an FsDataProvider and returns it as an [ICU4XDataProvider]. Requires the provider_fs Cargo feature. Not supported in WASM.

See the Rust documentation for FsDataProvider for more information.

create_test()

ICU4XDataProvider ICU4XDataProvider::create_test ( )

inlinestatic

Deprecated

Use create_compiled().

enable_locale_fallback()

diplomat::result< std::monostate, ICU4XError > ICU4XDataProvider::enable_locale_fallback ( )

inline

Enables locale fallbacking for data requests made to this provider.

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

See the Rust documentation for try_new for more information.

Additional information: 1

enable_locale_fallback_with()

diplomat::result< std::monostate, ICU4XError > ICU4XDataProvider::enable_locale_fallback_with ( const ICU4XLocaleFallbacker & fallbacker )

inline

See the Rust documentation for new_with_fallbacker for more information.

Additional information: 1

fork_by_key()

diplomat::result< std::monostate, ICU4XError > ICU4XDataProvider::fork_by_key ( ICU4XDataProvider & other )

inline

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.

See the Rust documentation for ForkByKeyProvider for more information.

fork_by_locale()

diplomat::result< std::monostate, ICU4XError > ICU4XDataProvider::fork_by_locale ( ICU4XDataProvider & other )

inline

Same as fork_by_key but forks by locale instead of key.

See the Rust documentation for MissingLocalePredicate for more information.

operator=()

ICU4XDataProvider & ICU4XDataProvider::operator= ( ICU4XDataProvider && other )
