Enum regex_syntax::ast::ClassSetItem

pub enum ClassSetItem {
    Empty(Span),
    Literal(Literal),
    Range(ClassSetRange),
    Ascii(ClassAscii),
    Unicode(ClassUnicode),
    Perl(ClassPerl),
    Bracketed(Box<ClassBracketed>),
    Union(ClassSetUnion),
}

A single component of a character class set.

Variants

Empty(Span)

An empty item.

Note that a bracketed character class cannot contain a single empty item. Empty items can appear when using one of the binary operators. For example, [&&] is the intersection of two empty classes.

Tuple Fields of Empty

0: Span

Literal(Literal)

A single literal.

Tuple Fields of Literal

0: Literal

Range(ClassSetRange)

A range between two literals.

Tuple Fields of Range

0: ClassSetRange

Ascii(ClassAscii)

An ASCII character class, e.g., [:alnum:] or [:punct:].

Tuple Fields of Ascii

0: ClassAscii

Unicode(ClassUnicode)

A Unicode character class, e.g., \pL or \p{Greek}.

Tuple Fields of Unicode

0: ClassUnicode

Perl(ClassPerl)

A perl character class, e.g., \d or \W.

Tuple Fields of Perl

0: ClassPerl

Bracketed(Box<ClassBracketed>)

A bracketed character class set, which may contain zero or more character ranges and/or zero or more nested classes. e.g., [a-zA-Z\pL].

Tuple Fields of Bracketed

0: Box<ClassBracketed>

Union(ClassSetUnion)

A union of items.

Tuple Fields of Union

0: ClassSetUnion
