impl LineBreak

Source

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

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

Enabled with the compiled_data Cargo feature.

§Example
use icu::properties::LineBreak;

let lookup = LineBreak::name_to_enum_mapper();
// short name for value
assert_eq!(lookup.get_strict("BK"), Some(LineBreak::MandatoryBreak));
assert_eq!(lookup.get_strict("AL"), Some(LineBreak::Alphabetic));
// long name for value
assert_eq!(lookup.get_strict("Mandatory_Break"), Some(LineBreak::MandatoryBreak));
assert_eq!(lookup.get_strict("Alphabetic"), Some(LineBreak::Alphabetic));
// name has incorrect casing and dash instead of underscore
assert_eq!(lookup.get_strict("mandatory-Break"), None);
// loose matching of name
assert_eq!(lookup.get_loose("mandatory-Break"), Some(LineBreak::MandatoryBreak));
// fake property
assert_eq!(lookup.get_strict("Stochastic_Break"), None);
