Expand description

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.

§

Literal(Literal)

A single literal.

§

Range(ClassSetRange)

A range between two literals.

§

Ascii(ClassAscii)

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

§

Unicode(ClassUnicode)

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

§

Perl(ClassPerl)

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

§

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].

§

Union(ClassSetUnion)

A union of items.
