All Implemented Interfaces:

StreamBase, WriteStream<Req>
```
public class GrpcClientRequest<Req,Resp>
extends GrpcWriteStream<Req>
```
A request to a gRPC server.
You interact with the remote service with gRPC generated messages or protobuf encoded messages.
Before sending a request you need to set #serviceName) and #methodName) or alternatively the service fullMethodName(java.lang.String).
Writing a request message will send the request to the service:
- To send a unary request, just call
- To send a streaming request, call any time you need and then WriteStream.end()
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

```
public GrpcClientRequest<Req,Resp> setWriteQueueMaxSize(int maxSize)

    Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pipe for an example of this being used.
    The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2.
    
    Specified by:
    
    drainHandler in interface WriteStream<Req>
    
    Overrides:
