Struct regex_syntax::ast::ClassUnicode

pub struct ClassUnicode {
    pub span: Span,
    pub negated: bool,
    pub kind: ClassUnicodeKind,
}

A Unicode character class.

Fields

span: Span

The span of this class.

negated: bool

Whether this class is negated or not.

Note: be careful when using this attribute. This specifically refers to whether the class is written as \p or \P, where the latter is negated = true. However, it also possible to write something like \P{scx!=Katakana} which is actually equivalent to \p{scx=Katakana} and is therefore not actually negated even though negated = true here. To test whether this class is truly negated or not, use the is_negated method.

kind: ClassUnicodeKind

The kind of Unicode class.

Implementations

impl ClassUnicode

pub fn is_negated(&self) -> bool

Returns true if this class has been negated.

Note that this takes the Unicode op into account, if it’s present. e.g., is_negated for \P{scx!=Katakana} will return false.

Trait Implementations

impl Clone for ClassUnicode

fn clone(&self) -> ClassUnicode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClassUnicode

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

Formats the value using the given formatter.

impl PartialEq for ClassUnicode

fn eq(&self, other: &ClassUnicode) -> 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.
