RegEx class

A validation rule for checking if a value matches a specified regular expression pattern.

The RegEx class is a concrete implementation of the FormifyRule abstract class. It is used to validate whether a value matches a specified regular expression pattern.

This rule checks if the input value matches the provided pattern using a regular expression. If the value does not match the pattern, an error message is generated.
