Struct UnicodeSetDataBorrowed

pub struct UnicodeSetDataBorrowed<'a> { /* private fields */ }

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

Implementations

impl<'a> UnicodeSetDataBorrowed<'a>

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

Check if the set contains the string. Strings consisting of one character are treated as a character/code point.

This matches ICU behavior for ICU’s UnicodeSet.

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

Check if the set contains a character as a UTF32 code unit

pub fn contains_char(&self, ch: char) -> bool

Check if the set contains the code point corresponding to the Rust character.

impl UnicodeSetDataBorrowed<'static>

pub const fn static_to_owned(self) -> UnicodeSetData

Cheaply converts a [UnicodeSetDataBorrowed<'static>] into a UnicodeSetData.

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

Trait Implementations
