/**
 * A gRPC server based on Vert.x HTTP server.
 *
 *  The server can be used as a {@link io.vertx.rxjava3.core.http.HttpServer} handler or mounted as a Vert.x Web handler.
 *
 * 
 Unlike traditional gRPC servers, this server 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 server exposes 2 levels of handlers
 *
 * 

 *   a Protobuf message {@link io.vertx.rxjava3.grpc.server.GrpcServer #callHandler(Handler) handler}: {@link io.vertx.rxjava3.grpc.server.GrpcServerRequest}/{@link io.vertx.rxjava3.grpc.server.GrpcServerResponse} with Protobuf message that handles any method call in a generic way
 *   a gRPC message {@link io.vertx.rxjava3.grpc.server.GrpcServer #callHandler(MethodDescriptor, Handler) handler}: {@link io.vertx.rxjava3.grpc.server.GrpcServerRequest}/{@link io.vertx.rxjava3.grpc.server.GrpcServerRequest} with gRPC messages that handles specific service method calls
 * 
 *
 *
 * 
 * NOTE: This class has been automatically generated from the {@link io.vertx.grpc.server.GrpcServer original} non RX-ified interface using Vert.x codegen.
