Struct icu::collections::codepointinvliststringlist::CodePointInversionListAndStringList

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

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

impl<'data> CodePointInversionListAndStringList<'data>

pub fn try_from( cp_inv_list: CodePointInversionList<'data>, str_list: VarZeroVec<'data, str, Index16> ) -> Result<CodePointInversionListAndStringList<'data>, CodePointInversionListAndStringListError>

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(&self, s: &str) -> bool

Examples

use icu_collections::codepointinvlist::CodePointInversionList;

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"));

fn clone(&self) -> CodePointInversionListAndStringList<'data>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'data> Debug for CodePointInversionListAndStringList<'data>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de, 'data> Deserialize<'de> for CodePointInversionListAndStringList<'data>where 'de: 'data,

fn deserialize<__D>( __deserializer: __D ) -> Result<CodePointInversionListAndStringList<'data>, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> FromIterator<&'a str> for CodePointInversionListAndStringList<'_>

fn from_iter<I>(it: I) -> CodePointInversionListAndStringList<'_>where I: IntoIterator<Item = &'a str>,

impl<'data> PartialEq<CodePointInversionListAndStringList<'data>> for CodePointInversionListAndStringList<'data>

fn eq(&self, other: &CodePointInversionListAndStringList<'data>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> Yokeable<'a> for CodePointInversionListAndStringList<'static>

type Output = CodePointInversionListAndStringList<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform( &'a self ) -> &'a <CodePointInversionListAndStringList<'static> as Yokeable<'a>>::Output
