Description of problem

If we set proto like this in stream (take the example from : https://github.com/containerd/ttrpc-rust/blob/master/example/protocols/protos/streaming.proto)

rpc DivideStream(Sum) returns (stream Part);

If the Sum here contains i32 like

message Sum {
	int32 sum = 1;
	int32 num = 2;
}

and that all i32 values (sum and num) are 0.
⚠️To reproduce the problem, all i32 must be 0, if only sum is 0 or num is 0, then the connection will not lost

In the above case, the connection must be lost. The client side won't return any error and the server side won't receive anything.

This is pretty easy to reproduce, you can change

Expected result

server side receive the message

Actual result

The client side won't return any error and the server side won't receive anything.
