Struct CodePointSetDataBorrowed 

pub struct CodePointSetDataBorrowed<'a> { /* private fields */ }

A borrowed wrapper around code point set data, returned by CodePointSetData::as_borrowed(). More efficient to query.

Implementations

impl CodePointSetDataBorrowed<'static>

pub const fn new<P: BinaryProperty>() -> Self

Creates a new CodePointSetData for a BinaryProperty.

✨ Enabled with the compiled_data Cargo feature.

📚 Help choosing a constructor

pub const fn static_to_owned(self) -> CodePointSetData

Cheaply converts a CodePointSetDataBorrowed<'static> into a CodePointSetData.

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

impl<'a> CodePointSetDataBorrowed<'a>

pub fn contains(self, ch: char) -> bool

Check if the set contains a character

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

pub fn contains32(self, ch: u32) -> bool

See Self::contains.

pub fn iter_ranges(self) -> impl Iterator<Item = RangeInclusive<u32>> + 'a

included in the CodePointSetData

Ranges are returned as RangeInclusive, which is inclusive of its end bound value. An end-inclusive behavior matches the ICU4C/J behavior of ranges, ex: UnicodeSet::contains(UChar32 start, UChar32 end).

Example

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

let alphabetic = CodePointSetData::new::<Alphabetic>();
let mut ranges = alphabetic.iter_ranges();

assert_eq!(Some(0x0041..=0x005A), ranges.next()); // 'A'..'Z'
assert_eq!(Some(0x0061..=0x007A), ranges.next()); // 'a'..'z'

pub fn iter_ranges_complemented( self, ) -> impl Iterator<Item = RangeInclusive<u32>> + 'a

not included in the CodePointSetData

Ranges are returned as RangeInclusive, which is inclusive of its end bound value. An end-inclusive behavior matches the ICU4C/J behavior of ranges, ex: UnicodeSet::contains(UChar32 start, UChar32 end).

Example

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

let alphabetic = CodePointSetData::new::<Alphabetic>();
let mut ranges = alphabetic.iter_ranges();

assert_eq!(Some(0x0041..=0x005A), ranges.next()); // 'A'..'Z'
assert_eq!(Some(0x0061..=0x007A), ranges.next()); // 'a'..'z'
