Struct icu::properties::names::PropertyValueNameToEnumMapperBorrowed

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

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

Implementations

impl<T> PropertyValueNameToEnumMapperBorrowed<'_, T>where T: TrieValue,

pub fn get_strict_u16(&self, name: &str) -> Option<u16>

Get the property value as a u16, doing a strict search looking for names that match exactly

Example

use icu_properties::GeneralCategory;

let lookup =
    GeneralCategory::get_name_to_enum_mapper(&icu_testdata::unstable())
        .expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(
    lookup.get_strict_u16("Lu"),
    Some(GeneralCategory::UppercaseLetter as u16)
);
assert_eq!(
    lookup.get_strict_u16("Uppercase_Letter"),
    Some(GeneralCategory::UppercaseLetter as u16)
);
// does not do loose matching
assert_eq!(lookup.get_strict_u16("UppercaseLetter"), None);

pub fn get_strict(&self, name: &str) -> Option<T>

Get the property value as a T, doing a strict search looking for names that match exactly

Example

use icu_properties::GeneralCategory;

let lookup =
    GeneralCategory::get_name_to_enum_mapper(&icu_testdata::unstable())
        .expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(
    lookup.get_strict("Lu"),
    Some(GeneralCategory::UppercaseLetter)
);
assert_eq!(
    lookup.get_strict("Uppercase_Letter"),
    Some(GeneralCategory::UppercaseLetter)
);
// does not do loose matching
assert_eq!(lookup.get_strict("UppercaseLetter"), None);

pub fn get_loose_u16(&self, name: &str) -> Option<u16>

Get the property value as a u16, doing a loose search looking for names that match case-insensitively, ignoring ASCII hyphens, underscores, and whitespaces.

Example

use icu_properties::GeneralCategory;

let lookup =
    GeneralCategory::get_name_to_enum_mapper(&icu_testdata::unstable())
        .expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(
    lookup.get_loose_u16("Lu"),
    Some(GeneralCategory::UppercaseLetter as u16)
);
assert_eq!(
    lookup.get_loose_u16("Uppercase_Letter"),
    Some(GeneralCategory::UppercaseLetter as u16)
);
// does do loose matching
assert_eq!(
    lookup.get_loose_u16("UppercaseLetter"),
    Some(GeneralCategory::UppercaseLetter as u16)
);

pub fn get_loose(&self, name: &str) -> Option<T>

Get the property value as a T, doing a loose search looking for names that match case-insensitively, ignoring ASCII hyphens, underscores, and whitespaces.

Example

use icu_properties::GeneralCategory;

let lookup =
    GeneralCategory::get_name_to_enum_mapper(&icu_testdata::unstable())
        .expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(
    lookup.get_loose("Lu"),
    Some(GeneralCategory::UppercaseLetter)
);
assert_eq!(
    lookup.get_loose("Uppercase_Letter"),
    Some(GeneralCategory::UppercaseLetter)
);
// does do loose matching
assert_eq!(
    lookup.get_loose("UppercaseLetter"),
    Some(GeneralCategory::UppercaseLetter)
);
