Struct icu_properties::props::PropertyEnumToValueNameSparseMapperBorrowed

pub struct PropertyEnumToValueNameSparseMapperBorrowed<'a, T> {
    map: &'a PropertyEnumToValueNameSparseMapV1<'a>,
    markers: PhantomData<fn(_: T)>,
}

A borrowed wrapper around property value name-to-enum data, returned by PropertyEnumToValueNameSparseMapper::as_borrowed(). More efficient to query.

Fields

map: &'a PropertyEnumToValueNameSparseMapV1<'a>

markers: PhantomData<fn(_: T)>

Implementations

impl<T: TrieValue> PropertyEnumToValueNameSparseMapperBorrowed<'_, T>

pub fn get(&self, property: T) -> Option<&str>

Get the property name given a value

Example

use icu::properties::CanonicalCombiningClass;

let lookup = CanonicalCombiningClass::enum_to_long_name_mapper();
assert_eq!(
    lookup.get(CanonicalCombiningClass::KanaVoicing),
    Some("Kana_Voicing")
);
assert_eq!(
    lookup.get(CanonicalCombiningClass::AboveLeft),
    Some("Above_Left")
);

impl<T: TrieValue> PropertyEnumToValueNameSparseMapperBorrowed<'static, T>

pub const fn static_to_owned(self) -> PropertyEnumToValueNameSparseMapper<T>

Cheaply converts a [PropertyEnumToValueNameSparseMapperBorrowed<'static>] into a PropertyEnumToValueNameSparseMapper.

Note: Due to branching and indirection, using PropertyEnumToValueNameSparseMapper might inhibit some compile-time optimizations that are possible with PropertyEnumToValueNameSparseMapperBorrowed.
