pub struct ExemplarCharactersBorrowed<'a> { /* private fields */ }
Expand description

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

Implementations§

source§

impl ExemplarCharactersBorrowed<'static>

source

pub const fn static_to_owned(self) -> ExemplarCharacters

Cheaply converts a [ExemplarCharactersBorrowed<'static>] into a ExemplarCharacters.

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

Methods from Deref<Target = CodePointInversionListAndStringList<'a>>§

source

pub fn size(&self) -> usize

Returns the number of elements in this set (its cardinality). Note than the elements of a set may include both individual codepoints and strings.

source

pub fn has_strings(&self) -> bool

Return true if this set contains multi-code point strings or the empty string.

source

pub fn contains_str(&self, s: &str) -> bool

§Examples
use icu::collections::codepointinvlist::CodePointInversionList;
use icu::collections::codepointinvliststringlist::CodePointInversionListAndStringList;
use zerovec::VarZeroVec;

let cp_slice = &[0, 0x1_0000, 0x10_FFFF, 0x11_0000];
let cp_list =

let str_slice = &["", "bmp_max", "unicode_max", "zero"];
let str_list = VarZeroVec::<str>::from(str_slice);

let cpilsl = CodePointInversionListAndStringList::try_from(cp_list, str_list).unwrap();

assert!(cpilsl.contains_str("bmp_max"));
assert!(cpilsl.contains_str(""));
assert!(cpilsl.contains_str("A"));

assert!(!cpilsl.contains_str("bazinga!"));
source

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

§Examples
use icu::collections::codepointinvlist::CodePointInversionList;
