Struct PropertyEnumToValueNameLinearMapperBorrowed

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

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

Implementations

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

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

Get the property name given a value

Example

use icu::properties::GeneralCategory;

let lookup = GeneralCategory::enum_to_short_name_mapper();
assert_eq!(lookup.get(GeneralCategory::UppercaseLetter), Some("Lu"));
assert_eq!(lookup.get(GeneralCategory::DashPunctuation), Some("Pd"));

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

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

Cheaply converts a [PropertyEnumToValueNameLinearMapperBorrowed<'static>] into a PropertyEnumToValueNameLinearMapper.

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