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: TrieValue> PropertyParserBorrowed<'_, T>
impl<T: TrieValue> PropertyParserBorrowed<'_, T>
sourcepub fn get_strict_u16(&self, name: &str) -> Option<u16>
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::props::GeneralCategory;
use icu::properties::PropertyParser;
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);
sourcepub fn get_strict(&self, name: &str) -> Option<T>
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::props::GeneralCategory;
use icu::properties::PropertyParser;
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);
sourcepub fn get_loose_u16(&self, name: &str) -> Option<u16>
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::props::GeneralCategory;
use icu::properties::PropertyParser;
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)
);
sourcepub fn get_loose(&self, name: &str) -> Option<T>
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::props::GeneralCategory;
use icu::properties::PropertyParser;
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: TrieValue> PropertyParserBorrowed<'static, T>
sourcepub fn new() -> Selfwhere
T: ParseableEnumeratedProperty,
pub fn new() -> Selfwhere
T: ParseableEnumeratedProperty,
Creates a new instance of PropertyParserBorrowed<T>
using compiled data.
✨ Enabled with the compiled_data
Cargo feature.
sourcepub const fn static_to_owned(self) -> PropertyParser<T>
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
.
