A new interface is added to the server generated file

[hdheid]

Add server interface implementation

proto --go_out=.arrist.proto --go_out=.arrist.proto to generate arrist.svr.go. But when I write all the function logic and use the command again, all my code is gone.

So I borrowed from grpc and implemented an extra interface, which we can implement outside the file arith.svr.go, so we can not only successfully call the corresponding method, but also don't have to worry about writing logic overwritten! The updated arist.svr.go file looks like this:

// Code generated by protoc-gen-tinyrpc. DO NOT EDIT.

package message

// ArithServiceServer You need to define a struct to implement these methods and then call them
type ArithServiceServer interface {
	Add(args *ArithRequest, reply *ArithResponse) error
	Sub(args *ArithRequest, reply *ArithResponse) error
	Mul(args *ArithRequest, reply *ArithResponse) error
	Div(args *ArithRequest, reply *ArithResponse) error
}

// ArithService Defining Computational Digital Services
type ArithService struct{}

// Add addition
func (this *ArithService) Add(args *ArithRequest, reply *ArithResponse) error {
	// define your service ...
	return nil
}

// Sub subtraction
func (this *ArithService) Sub(args *ArithRequest, reply *ArithResponse) error {
	// define your service ...
	return nil
}

// Mul multiplication
func (this *ArithService) Mul(args *ArithRequest, reply *ArithResponse) error {
	// define your service ...
	return nil
}

// Div division
func (this *ArithService) Div(args *ArithRequest, reply *ArithResponse) error {
	// define your service ...
	return nil
}

The code section only changes the code in tinerpc/protoc-gen-tinyrpc/main.go. Add the following code to the Generate method:

// modified part
t.P("// Code generated by protoc-gen-tinyrpc. DO NOT EDIT.")

// new additions
comment := fmt.Sprintf("// %sServer You need to define a struct to implement these methods and then call them\n", s.Desc.Name())
serviceInterface := fmt.Sprintf("%stype %sServer interface{",
    comment, s.Desc.Name())
t.P(serviceInterface)
for _, m := range s.Methods {
    funcCode := fmt.Sprintf("%s(args *%s, reply *%s) error",
        m.Desc.Name(), m.Input.Desc.Name(), m.Output.Desc.Name())
    t.P(funcCode)
}
t.P("}")

I have tested go fmt and go vet locally.And generated corresponding files to implement the interface. There is no problem after testing.
