Struct icu_properties::sets::CodePointSetDataBorrowed
source · pub struct CodePointSetDataBorrowed<'a> {
set: &'a PropertyCodePointSetV1<'a>,
}
Expand description
A borrowed wrapper around code point set data, returned by
CodePointSetData::as_borrowed()
. More efficient to query.

§set: &'a PropertyCodePointSetV1<'a>
Implementations§
source§impl CodePointSetDataBorrowed<'static>
impl CodePointSetDataBorrowed<'static>
sourcepub const fn static_to_owned(self) -> CodePointSetData
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>
sourcepub fn contains(self, ch: char) -> bool
pub fn contains(self, ch: char) -> bool
Check if the set contains a character
use icu::properties::sets;
let alphabetic = sets::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
sourcepub fn contains32(self, ch: u32) -> bool
pub fn contains32(self, ch: u32) -> bool
Check if the set contains a character as a UTF32 code unit
use icu::properties::sets;
let alphabetic = sets::alphabetic();
assert!(!alphabetic.contains32(0x0A69)); // U+0A69 GURMUKHI DIGIT THREE
assert!(alphabetic.contains32(0x00C4)); // U+00C4 LATIN CAPITAL LETTER A WITH DIAERESIS
sourcepub fn iter_ranges(self) -> impl Iterator<Item = RangeInclusive<u32>> + 'a
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::sets;
let alphabetic = sets::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'
sourcepub fn iter_ranges_complemented(
self,
) -> impl Iterator<Item = RangeInclusive<u32>> + 'a
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::sets;
let alphabetic = sets::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'
