Struct icu::properties::names::PropertyEnumToValueNameSparseMapper

pub struct PropertyEnumToValueNameSparseMapper<T> { /* private fields */ }

A struct capable of looking up a property name from a value Access its data by calling Self::as_borrowed() and using the methods on PropertyEnumToValueNameSparseMapperBorrowed.

This mapper is used for properties with sparse values, like CanonicalCombiningClass. It may be obtained using methods like CanonicalCombiningClass::get_enum_to_long_name_mapper().

The name returned may be a short ("KV") or long ("Kana_Voicing") name, depending on the constructor used.

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")
);

Implementations

impl<T> PropertyEnumToValueNameSparseMapper<T>

where T: TrieValue,

pub fn as_borrowed(&self) -> PropertyEnumToValueNameSparseMapperBorrowed<'_, T>

Construct a borrowed version of this type that can be queried.

This avoids a potential small underlying cost per API call (like get_static()) by consolidating it up front.

Trait Implementations

impl<T> Debug for PropertyEnumToValueNameSparseMapper<T>

where T: Debug,

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

Formats the value using the given formatter.
