Expand description

A wrapper around UnicodeSet data (characters and strings)

Implementations§

source§

impl ExemplarCharacters

source

pub fn as_borrowed(&self) -> ExemplarCharactersBorrowed<'_>

Construct a borrowed version of this type that can be queried.

This avoids a potential small underlying cost per API call (ex: contains()) by consolidating it up front.

impl ExemplarCharacters

source

pub fn try_new_main( locale: &DataLocale, ) -> Result<ExemplarCharactersBorrowed<'static>, DataError>

Get the “main” set of exemplar characters.

Enabled with the compiled_data Cargo feature.

§Examples
use icu::locale::locale;
use icu::locale::exemplar_chars::ExemplarCharacters;

let exemplars_main = ExemplarCharacters::try_new_main(&locale!("en").into())
    .expect("locale should be present");

assert!(exemplars_main.contains('a'));

assert!(exemplars_main.contains_str("a"));
assert!(!exemplars_main.contains_str("ä"));
assert!(!exemplars_main.contains_str("ng"));
assert!(!exemplars_main.contains_str("A"));
source

pub fn try_new_main_unstable( provider: &(impl DataProvider<ExemplarCharactersMainV1Marker> + ?Sized), locale: &DataLocale, ) -> Result<ExemplarCharacters, DataError>
