Custom validation directives for arguments and input fields

[korsNaike]

The essence of the problem: I wanted to implement a custom directive to check a string for matching a regular expression, for example:

input ChangePasswordInput {
    password: String @regex(pattern: "^(?=.*[A-ZА-Я])(?=.*[a-zа-я])(?=.*[0-9])(?=.*\\W).{8,}$", errorMessage: "Bad Request")
}

But I can't do this, no matter how hard I try, I tried to substitute the parse_value and parse_literal methods for the object in the "type" field of "GraphQLInputField", but this substitution will also affect the change in all other fields that use the same data type. Then I tried to make a copy of the object from the type field: "field.type = deepcopy(field.type)", but it didn't help, validation just stopped working. In this case, it would be convenient to have a field for the "GraphQLInputField" and "GraphQLArgument" classes to set a callback that would be called when receiving data to this input.
Such functionality would be useful for "INPUT_FIELD_DEFINITION" and for "ARGUMENT_DEFINITION".
