Struct regex_syntax::ast::ClassUnicode

source ·
pub struct ClassUnicode {
    pub span: Span,
    pub negated: bool,
    pub kind: ClassUnicodeKind,
}
Expand description

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§

source§

impl ClassUnicode

source

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.

impl PartialEq for ClassUnicode

source§

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