Struct icu_properties::PropertyNamesLongBorrowed

pub struct PropertyNamesLongBorrowed<'a, T: NamedEnumeratedProperty> { /* private fields */ }

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

Implementations

impl<T: NamedEnumeratedProperty> PropertyNamesLongBorrowed<'_, T>

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

Get the property name given a value

Example

use icu::properties::PropertyNamesLong;
use icu::properties::props::CanonicalCombiningClass;

let lookup = PropertyNamesLong::<CanonicalCombiningClass>::new();
assert_eq!(
    lookup.get(CanonicalCombiningClass::KanaVoicing),
    Some("Kana_Voicing")
);
assert_eq!(
    lookup.get(CanonicalCombiningClass::AboveLeft),
    Some("Above_Left")
);

impl<T: NamedEnumeratedProperty> PropertyNamesLongBorrowed<'static, T>

pub fn new() -> Self

Creates a new instance of PropertyNamesLongBorrowed<T>.

✨ Enabled with the compiled_data Cargo feature.

📚 Help choosing a constructor

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

Cheaply converts a [PropertyNamesLongBorrowed<'static>] into a PropertyNamesLong.

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

Trait Implementations
