But this guide shows you, more or less, how they are intended to be used.

### Using Pydantic's `exclude_unset` parameter { #using-pydantics-exclude-unset-parameter }

If you want to receive partial updates, it's very useful to use the parameter `exclude_unset` in Pydantic's model's `.model_dump()`.

Like `item.model_dump(exclude_unset=True)`.

Но в данном руководстве более или менее понятно, как они должны использоваться.

///

### Использование параметра `exclude_unset` в Pydantic { #using-pydantics-exclude-unset-parameter }

Если необходимо выполнить частичное обновление, то очень полезно использовать параметр `exclude_unset` в методе `.model_dump()` модели Pydantic.

Например, `item.model_dump(exclude_unset=True)`.

Mas este guia te dá uma ideia de como eles são destinados a serem usados.

///

### Usando o parâmetro `exclude_unset` do Pydantic { #using-pydantics-exclude-unset-parameter }

Se você quiser receber atualizações parciais, é muito útil usar o parâmetro `exclude_unset` no método `.model_dump()` do modelo do Pydantic.

Como `item.model_dump(exclude_unset=True)`.

/// info | Informação

Aber dieser Leitfaden zeigt Ihnen mehr oder weniger, wie die beiden normalerweise verwendet werden.

### Pydantics `exclude_unset`-Parameter verwenden { #using-pydantics-exclude-unset-parameter }

Wenn Sie Teil-Aktualisierungen entgegennehmen, ist der `exclude_unset`-Parameter in der `.model_dump()`-Methode von Pydantic-Modellen sehr nützlich.

Wie in `item.model_dump(exclude_unset=True)`.

func RootCAs(certPool *x509.CertPool) OperatorOption {
	return func(args *OperatorDNS) {
		args.rootCAs = certPool
	}
}

// NewOperatorDNS - initialize a new K8S Operator DNS set/unset values.
func NewOperatorDNS(endpoint string, setters ...OperatorOption) (Store, error) {
	if endpoint == "" {
		return nil, errors.New("invalid argument")
	}

	args := &OperatorDNS{
		Endpoint: endpoint,
	}

        // Password is null, so callback is not set (remains null)
        assertNull(pc.getPassword());
    }

    @Test
    @DisplayName("handle: null password leaves PasswordCallback unset")
    void testHandleWithNullPasswordDoesNotSet() throws Exception {
        // Spy to override getPasswordAsCharArray() to return null
        JAASAuthenticator spyAuth = spy(new JAASAuthenticator("DOM", "user", null));

        // Properties set should override defaults
        assertTrue(config.isUseMultiChannel());
        assertEquals(8, config.getMaxChannels());

        // Unset properties should use defaults
        assertEquals(1, config.getChannelBindingPolicy());
        assertEquals("adaptive", config.getLoadBalancingStrategy());
        assertEquals(10, config.getChannelHealthCheckInterval());

Pero esta guía te muestra, más o menos, cómo se pretende que se usen.
