You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: greeter_mqant.pb.go
    path of file: ./repos/mqant/examples/proto/examples/greeter
    
    the code of the file until where you have to start completion: // Code generated by protoc-gen-go-hi. DO NOT EDIT.
// versions:

package greeter

// This is a compile-time assertion to ensure that this generated file
// is compatible with the kratos package it is being compiled against.

	if proxy == nil {
		return nil, ClientProxyIsNil
	}
	rsp = &Response{}
	err = mqrpc.Proto(rsp, func() (reply interface{}, err interface{}) {
		return proxy.cli.Call(context.TODO(), proxy.name, "hello", mqrpc.Param(req))
	})
	return rsp, err
