Struct PropertyEnumToValueNameSparseMapperBorrowed 

pub struct PropertyEnumToValueNameSparseMapperBorrowed<'a, T> { /* private fields */ }

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

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.

Trait Implementations

impl<'a, T: Clone> Clone for PropertyEnumToValueNameSparseMapperBorrowed<'a, T>

fn clone(&self) -> PropertyEnumToValueNameSparseMapperBorrowed<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for PropertyEnumToValueNameSparseMapperBorrowed<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: Copy> Copy for PropertyEnumToValueNameSparseMapperBorrowed<'a, 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.
