[−]

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.

Methods

impl ClassSetItem[src][−]
