Closure

The Hazaar Closure Class.

class Closure implements \JsonSerializable

Implements: JsonSerializable

This class is a wrapper around PHP's Closure class that allows for the serialization of closures. This is useful for storing closures in a database or transmitting them over a network.

It supports both standard closures and arrow functions (fn).

The class can serialize the closure code to a string and deserialize it back to a closure.

It also provides methods to invoke the closure, get its parameters, and fetch its code.
