`net/rpc`

Guided tour · Networking · pkg.go.dev →

A Go-specific RPC framework. Frozen — not developed further. For new systems prefer gRPC or Twirp.

What it looks like

Registered method signature

type Args struct{ A, B int }

type Calc struct{}
func (c *Calc) Add(args *Args, reply *int) error {
    *reply = args.A + args.B
    return nil
}

rpc.Register(&Calc{})
rpc.HandleHTTP()
http.ListenAndServe(":8080", nil)

Client

client, _ := rpc.DialHTTP("tcp", "localhost:8080")
var result int
client.Call("Calc.Add", Args{3, 4}, &result)
