Resultaria em algo equivalente a:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Ou mais exatamente, usando `user_dict` diretamente, com qualquer conteúdo que ele possa ter no futuro:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

    return password_hash.verify(plain_password, hashed_password)


def get_password_hash(password):
    return password_hash.hash(password)


def get_user(db, username: str):
    if username in db:
        user_dict = db[username]
        return UserInDB(**user_dict)


def authenticate_user(fake_db, username: str, password: str):
    user = get_user(fake_db, username)
    if not user:
        return False

    return password_hash.verify(plain_password, hashed_password)


def get_password_hash(password):
    return password_hash.hash(password)


def get_user(db, username: str):
    if username in db:
        user_dict = db[username]
        return UserInDB(**user_dict)


def authenticate_user(fake_db, username: str, password: str):
    user = get_user(fake_db, username)
    if not user:
        return False

    if (args.length != 4) {
      System.out.println("Usage: SampleServer <keystore> <password> <root file> <port>");
      return;
    }

    String keystoreFile = args[0];
    String password = args[1];
    String root = args[2];
    int port = Integer.parseInt(args[3]);

    SSLContext sslContext = sslContext(keystoreFile, password);
    SampleServer server = new SampleServer(sslContext, root, port);
    server.run();

                                "title": "Full Name",
                                "anyOf": [{"type": "string"}, {"type": "null"}],
