Struct icu_properties :: Script Copy item path

pub const fn name_to_enum_mapper() -> PropertyValueNameToEnumMapperBorrowed<'static, Script>

Return a PropertyValueNameToEnumMapper, capable of looking up values from strings for the Script enumerated property.

✨ Enabled with the compiled_data Cargo feature.

§Example

use icu::properties::Script;

let lookup = Script::name_to_enum_mapper();
// short name for value
assert_eq!(lookup.get_strict("Brah"), Some(Script::Brahmi));
assert_eq!(lookup.get_strict("Hang"), Some(Script::Hangul));
// long name for value
assert_eq!(lookup.get_strict("Brahmi"), Some(Script::Brahmi));
assert_eq!(lookup.get_strict("Hangul"), Some(Script::Hangul));
// name has incorrect casing
assert_eq!(lookup.get_strict("brahmi"), None);
// loose matching of name
assert_eq!(lookup.get_loose("brahmi"), Some(Script::Brahmi));
// fake property
assert_eq!(lookup.get_strict("Linear_Z"), None);
