pub struct CodePointInversionListAndStringList<'data> { /* private fields */ }
Expand description

A data structure providing a concrete implementation of a UnicodeSet (which represents a set of code points and strings) using an inversion list for the code points and a simple list-like structure to store and iterate over the strings.

Implementations

Returns a new CodePointInversionListAndStringList from both a CodePointInversionList for the code points and a VarZeroVec<str> of strings.

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

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

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 =
   CodePointInversionList::try_clone_from_inversion_list_slice(cp_slice).unwrap();
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("bmp_max"));
assert!(cpilsl.contains(""));
assert!(cpilsl.contains("A"));
assert!(cpilsl.contains("ቔ"));  // U+1254 ETHIOPIC SYLLABLE QHEE
assert!(!cpilsl.contains("bazinga!"));
