Struct icu_properties::props::PropertyEnumToValueNameLinearMapper

pub struct PropertyEnumToValueNameLinearMapper<T> {
    map: DataPayload<ErasedEnumToValueNameLinearMapV1Marker>,
    markers: PhantomData<fn(_: T)>,
}

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 PropertyEnumToValueNameLinearMapperBorrowed.

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

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

Example

use icu::properties::GeneralCategory;

let lookup = GeneralCategory::enum_to_long_name_mapper();
assert_eq!(
    lookup.get(GeneralCategory::UppercaseLetter),
    Some("Uppercase_Letter")
);
assert_eq!(
    lookup.get(GeneralCategory::DashPunctuation),
    Some("Dash_Punctuation")
);

Fields

map: DataPayload<ErasedEnumToValueNameLinearMapV1Marker>

markers: PhantomData<fn(_: T)>

Implementations

impl<T: TrieValue> PropertyEnumToValueNameLinearMapper<T>

pub fn as_borrowed(&self) -> PropertyEnumToValueNameLinearMapperBorrowed<'_, 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.

pub(crate) fn from_data<M>(data: DataPayload<M>) -> Self

where M: DataMarker<Yokeable = PropertyEnumToValueNameLinearMapV1<'static>>,

Construct a new one from loaded data

Typically it is preferable to use methods on individual property value types (like [Script::TBD()]) instead.

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

Formats the value using the given formatter.
