Struct icu::collections::codepointinvliststringlist::CodePointInversionListAndStringList

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

A data structure providing a concrete implementation of a set of code points and strings, using an inversion list for the code points.

This is what ICU4C calls a UnicodeSet.

Implementations

impl<'data> CodePointInversionListAndStringList<'data>

pub fn try_from( cp_inv_list: CodePointInversionList<'data>, str_list: VarZeroVec<'data, str>, ) -> Result<CodePointInversionListAndStringList<'data>, InvalidStringList>

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

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.

pub fn has_strings(&self) -> bool

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

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