pub struct PropertyValueNameToEnumMapperBorrowed<'a, T> {
    map: &'a PropertyValueNameToEnumMapV1<'a>,
    markers: PhantomData<fn() -> T>,
}
Expand description

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

Implementations§

source§

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

source

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::name_to_enum_mapper();
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);
source

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::name_to_enum_mapper();
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);
source

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::name_to_enum_mapper();
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)
);
source

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::name_to_enum_mapper();
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)
);

impl<T: TrieValue> PropertyValueNameToEnumMapperBorrowed<'static, T>

source

pub const fn static_to_owned(self) -> PropertyValueNameToEnumMapper<T>

Cheaply converts a [PropertyValueNameToEnumMapperBorrowed<'static>] into a PropertyValueNameToEnumMapper.

Note: Due to branching and indirection, using PropertyValueNameToEnumMapper might inhibit some compile-time optimizations that are possible with PropertyValueNameToEnumMapperBorrowed.
