Struct icu::properties::CodePointSetData

pub struct CodePointSetData { /* private fields */ }

A set of Unicode code points. Access its data via the borrowed version, CodePointSetDataBorrowed.

Example

use icu::properties::CodePointSetData;
use icu::properties::props::Alphabetic;

let alphabetic = CodePointSetData::new::<Alphabetic>();

assert!(!alphabetic.contains('3'));
assert!(!alphabetic.contains('੩'));  // U+0A69 GURMUKHI DIGIT THREE
assert!(alphabetic.contains('A'));
assert!(alphabetic.contains('Ä'));  // U+00C4 LATIN CAPITAL LETTER A WITH DIAERESIS

Implementations

impl CodePointSetData

pub const fn new<P>() -> CodePointSetDataBorrowed<'static>

where P: BinaryProperty,

Creates a new CodePointSetData for a BinaryProperty.

✨ Enabled with the compiled_data Cargo feature.

pub fn try_new_unstable<P>( provider: &(impl DataProvider<<P as BinaryProperty>::DataMarker> + ?Sized), ) -> Result<CodePointSetData, DataError>

where P: BinaryProperty,

A version of Self::new that uses custom data provided by a DataProvider.

pub fn as_borrowed(&self) -> CodePointSetDataBorrowed<'_>

Construct a borrowed version of this type that can be queried.

This owned version if returned by functions that use a runtime data provider.

pub fn from_code_point_inversion_list( set: CodePointInversionList<'static>, ) -> CodePointSetData

Construct a new owned CodePointInversionList

pub fn as_code_point_inversion_list( &self, ) -> Option<&CodePointInversionList<'_>>

Convert this type to a CodePointInversionList as a borrowed value.

The data backing this is extensible and supports multiple implementations. Currently it is always CodePointInversionList; however in the future more backends may be added, and users may select which at data generation time.

This method returns an Option in order to return None when the backing data provider cannot return a CodePointInversionList, or cannot do so within the expected constant time constraint.

pub fn to_code_point_inversion_list(&self) -> CodePointInversionList<'_>

Convert this type to a CodePointInversionList, borrowing if possible, otherwise allocating a new CodePointInversionList.

The data backing this is extensible and supports multiple implementations. Currently it is always CodePointInversionList; however in the future more backends may be added, and users may select which at data generation time.

The performance of the conversion to this specific return type will vary depending on the data structure that is backing self.

impl CodePointSetData

pub fn new_for_ecma262(prop: &[u8]) -> Option<CodePointSetDataBorrowed<'static>>

Returns a type capable of looking up values for a property specified as a string, as long as it is a binary property listed in ECMA-262, using strict matching on the names in the spec.

This handles every property required by ECMA-262 /u regular expressions, except for:

• Script and General_Category: handle these directly using property values parsed via [PropertyParser<GeneralCategory>] and [PropertyParser<Script>] if necessary.
• Script_Extensions: handle this directly using APIs from crate::script::ScriptWithExtensions
• General_Category mask values: Handle this alongside General_Category using [GeneralCategoryGroup], using property values parsed via [PropertyParser<GeneralCategory>] if necessary
• Assigned, All, and ASCII pseudoproperties: Handle these using their equivalent sets:
  • Any can be expressed as the range [\u{0}-\u{10FFFF}]
  • Assigned can be expressed as the inverse of the set gc=Cn (i.e., \P{gc=Cn}).
  • ASCII can be expressed as the range [\u{0}-\u{7F}]
• General_Category property values can themselves be treated like properties using a shorthand in ECMA262, simply create the corresponding GeneralCategory set.
