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.
