Mastering Go - Second Edition

The RPC server

The RPC server will be saved as RPCserver.go, and it is presented in five parts.

The first part of RPCserver.go is as follows:

package main 
 
import ( 
    "fmt" 
    "math" 
    "net" 
    "net/rpc" 
    "os" 
    "sharedRPC" 
) 

The second segment of RPCserver.go contains the following Go code:

type MyInterface struct{} 
 
func Power(x, y float64) float64 { 
    return math.Pow(x, y) 
} 
 
func (t *MyInterface) Multiply(arguments *sharedRPC.MyFloats, reply *float64) error { 
    *reply = arguments.A1 * arguments.A2 
    return nil 
} 
 
func (t *MyInterface) Power(arguments *sharedRPC.MyFloats, reply *float64) error { 
    *reply = Power(arguments.A1, arguments.A2) 
    return nil 
} 

In the preceding Go code, the RPC server implements the desired interface, as well as a helper function named ...
