Bir veri doğrulama sistemi olmazsa bütün bu kontrolleri koda dökerek kendiniz yapmak zorunda kalırdınız.

Marshmallow bu özellikleri sağlamak için geliştirilmişti. Benim de geçmişte oldukça sık kullandığım harika bir kütüphanedir.

        int[] versionMinors = { 1, 0, 0 };
        int[] serverTypes = { 0x00000801, 0x00000809, 0x0000101B }; // Various server types
        String[] comments = { "Workstation", "File server", "Domain Controller" };

        // Set converter and number of entries
        setConverter(response, 0);
        setNumEntries(response, numServers);

        // Calculate total buffer size

* Validerà che esiste un `item_id` nel percorso delle richieste `GET` e `PUT`.
* Validerà che `item_id` sia di tipo `int` per le richieste `GET` e `PUT`.
    * Se non lo è, il client vedrà un errore chiaro e utile.
* Controllerà se ci sia un parametro opzionale chiamato `q` (per esempio `http://127.0.0.1:8000/items/foo?q=somequery`) per le richieste `GET`.
    * Siccome il parametro `q` è dichiarato con `= None`, è opzionale.
