Package io.vertx.rxjava3.grpc.client

## Class GrpcClient

- java.lang.Object
- - io.vertx.rxjava3.grpc.client.GrpcClient

- All Implemented Interfaces:
    `io.vertx.lang.rx.RxDelegate`

      public class GrpcClient
      extends Object
      implements io.vertx.lang.rx.RxDelegate

  A gRPC client for Vert.x

  Unlike traditional gRPC clients, this client does not rely on a generated RPC interface to interact with the service.

  Instead, you can interact with the service with a request/response interfaces and gRPC messages, very much like a traditional client.

  The client handles only the gRPC protocol and does not encode/decode protobuf messages.

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.
