Returning any error will also cancel the stream remotely.

CAREFUL: When utilizing two-way communication, it is important to ensure that the remote handler is not blocked on a send.
If the remote handler is blocked on a send, and the client is trying to send without the remote receiving, 
the operation would become deadlocked if the channels are full.

### Typed handlers

Java's built-in serialization mechanism is often slower compared to other serialization solutions.
This is due to Java's use of reflection and the need to maintain a lot of metadata.

- **Size of Serialized Data:**
Java serialization tends to produce larger serialized objects because it includes class metadata and other overhead.

- **Flexibility and Control:**

    /**
     * @param request
     * @param params
     * @return response message
     * @throws CIFSException
     */
    <T extends CommonServerMessageBlockResponse> T send ( Request<T> request, RequestParam... params ) throws CIFSException;

	QueueLength int

	// TotalMessages is the total number of messages sent in the lifetime of the target
	TotalMessages int64

	// FailedMessages should log message count that failed to send.
	FailedMessages int64

                if (r.byteCount > 0 && pad > 0 && pad < 4)
                    readn( in, BUF, 4 + off, pad);

Você pode definir uma sobreposição de dependência para uma dependência que é utilizada em qualquer lugar da sua aplicação **FastAPI**.

A dependência original pode estar sendo utilizada em uma *função de operação de rota*, um *docorador de operação de rota* (quando você não utiliza o valor retornado), uma chamada ao `.include_router()`, etc.

O FastAPI ainda poderá sobrescrevê-lo.
