Struct icu::properties::PropertyParserBorrowed

source ·
pub struct PropertyParserBorrowed<'a, T> { /* private fields */ }
Expand description

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

Implementations§

source§

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

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::PropertyParser;
use icu::properties::props::GeneralCategory;

let lookup = PropertyParser::<GeneralCategory>::new();
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::PropertyParser;
use icu::properties::props::GeneralCategory;

let lookup = PropertyParser::<GeneralCategory>::new();
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::PropertyParser;
use icu::properties::props::GeneralCategory;

let lookup = PropertyParser::<GeneralCategory>::new();
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::PropertyParser;
use icu::properties::props::GeneralCategory;

let lookup = PropertyParser::<GeneralCategory>::new();
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> PropertyParserBorrowed<'static, T>
where T: TrieValue,

source

pub fn new() -> PropertyParserBorrowed<'static, T>

Creates a new instance of PropertyParserBorrowed<T> using compiled data.

Enabled with the compiled_data Cargo feature.

📚 Help choosing a constructor

source

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

Cheaply converts a [PropertyParserBorrowed<'static>] into a PropertyParser.

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