Struct 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<'a, T: NamedEnumeratedProperty> PropertyNamesLongBorrowed<'a, T>

pub fn get(self, property: T) -> Option<&'a str>

Get the property name given a value

Example

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

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 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.

This is currently not const unlike other static_to_owned() functions since it needs const traits to do that safely

Trait Implementations

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

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

fn default() -> Self

Returns the “default value” for a type.

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
