Struct icu::properties::names::PropertyEnumToValueNameLinearMapper
source · pub struct PropertyEnumToValueNameLinearMapper<T> { /* private fields */ }
Expand description
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::get_enum_to_long_name_mapper(
&icu_testdata::unstable(),
)
.expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(
lookup.get(GeneralCategory::UppercaseLetter),
Some("Uppercase_Letter")
);
assert_eq!(
lookup.get(GeneralCategory::DashPunctuation),
Some("Dash_Punctuation")
);

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.
