Struct icu::properties::PropertyNamesShortBorrowed
source · pub struct PropertyNamesShortBorrowed<'a, T>where
T: NamedEnumeratedProperty,{ /* private fields */ }
Expand description
A borrowed wrapper around property value name-to-enum data, returned by
PropertyNamesShort::as_borrowed()
. More efficient to query.
Implementations§
source§impl<T> PropertyNamesShortBorrowed<'_, T>where
T: NamedEnumeratedProperty,
impl<T> PropertyNamesShortBorrowed<'_, T>where
T: NamedEnumeratedProperty,
sourcepub fn get(&self, property: T) -> Option<&str>
pub fn get(&self, property: T) -> Option<&str>
Get the property name given a value
§Example
use icu::properties::PropertyNamesShort;
use icu::properties::props::CanonicalCombiningClass;
let lookup = PropertyNamesShort::<CanonicalCombiningClass>::new();
assert_eq!(
lookup.get(CanonicalCombiningClass::KanaVoicing),
Some("KV")
);
assert_eq!(
lookup.get(CanonicalCombiningClass::AboveLeft),
Some("AL")
);
source§impl PropertyNamesShortBorrowed<'_, Script>
impl PropertyNamesShortBorrowed<'_, Script>
sourcepub fn get_locale_script(&self, property: Script) -> Option<Script>
pub fn get_locale_script(&self, property: Script) -> Option<Script>
Gets the “name” of a script property as a icu::locale::subtags::Script
.
This method is available only on PropertyNamesShortBorrowed<Script>
.
§Example
use icu::properties::PropertyNamesShort;
use icu::properties::props::Script;
use icu::locale::subtags::script;
let lookup = PropertyNamesShort::<Script>::new();
assert_eq!(lookup.get_locale_script(Script::Brahmi), Some(script!("Brah")));
assert_eq!(lookup.get_locale_script(Script::Hangul), Some(script!("Hang")));
For the reverse direction, use property parsing as normal:
use icu::properties::PropertyParser;
use icu::properties::props::Script;
use icu::locale::subtags::script;
let parser = PropertyParser::<Script>::new();
assert_eq!(parser.get_strict(script!("Brah").as_str()), Some(Script::Brahmi));
assert_eq!(parser.get_strict(script!("Hang").as_str()), Some(Script::Hangul));

T: NamedEnumeratedProperty,
impl<T> PropertyNamesShortBorrowed<'static, T>where
T: NamedEnumeratedProperty,
sourcepub fn new() -> PropertyNamesShortBorrowed<'static, T>
pub fn new() -> PropertyNamesShortBorrowed<'static, T>
Creates a new instance of PropertyNamesShortBorrowed<T>
.
✨ Enabled with the compiled_data
Cargo feature.
sourcepub const fn static_to_owned(self) -> PropertyNamesShort<T>
pub const fn static_to_owned(self) -> PropertyNamesShort<T>
Cheaply converts a [PropertyNamesShortBorrowed<'static>
] into a PropertyNamesShort
.
Note: Due to branching and indirection, using PropertyNamesShort
might inhibit some
compile-time optimizations that are possible with PropertyNamesShortBorrowed
.
