Satisfy(Rc<dyn Fn(&T) -> bool>)

Like a [character class] in regex. Regex that matches any values that satisfy the given predicate.

NotSatisfy(Rc<dyn Fn(&T) -> bool>)

Like a [^character class] in regex. Regex that matches any values that not satisfy the given predicate.

Concat(Rc<Regex<T>>, Rc<Regex<T>>)

Like a RS in regex. Concatenate two regex.

Group(Rc<Regex<T>>)

Like a (R) in regex. Numbered capturing group (submatch).

NamedGroup(String, Rc<Regex<T>>)

Like a (?<name>R) in regex. Numbered capturing group (submatch).

NonCapturingGroup(Rc<Regex<T>>)

Like a (?:R) in regex. Numbered non-capturing group.

Or(Rc<Regex<T>>, Rc<Regex<T>>)

Like a R|S in regex. Regex alternation.

ZeroOrOne(Rc<Regex<T>>, bool)

Like a ?, ?? in regex. Regex zero or one.

Repeat0(Rc<Regex<T>>, bool)

Like a *, *? in regex. Regex zero or one.

Repeat1(Rc<Regex<T>>, bool)

Like a +, +? in regex. Regex one or more.

RepeatN(Rc<Regex<T>>, usize)

Like a {n} in regex. Exactly N-times.

RepeatMinMax(Rc<Regex<T>>, usize, Option<usize>, bool)

Like a {n,m}, {n,m}? or {n,}, {n,}? in regex. n or n+1 or .. m times.
