Callback

• Callback(callable $callback)

This is a wildcard validator, it uses a function name, method or closure to validate something:

v::callback('is_int')->validate(10); // true

(Please note that this is a sample, the IntVal() validator is much better).

As in Call(), you can pass a method or closure to it.
