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: main.go
    path of file: ./repos/moby/integration/plugin/logging/cmd/close_on_start
    
    the code of the file until where you have to start completion: package main

import (
	"encoding/json"
	"fmt"
	"net"
	"net/http"
	"os"
	"time"
)

type start struct {
	File string
}

func main() {
	l, err := net.Listen("unix", "/run/docker/plugins/plugin.sock")
	if err != nil {
		panic(err)
	}

	mux := http.NewServeMux()
	mux.HandleFunc("/LogDriver.StartLogging", func(w http.ResponseWriter, req *http.Request) {
		startReq := &start{}
		i
    
func main() {
	l, err := net.Listen("unix", "/run/docker/plugins/plugin.sock")
	if err != nil {
		panic(err)
	}

	mux := http.NewServeMux()
	mux.HandleFunc("/LogDriver.StartLogging", func(w http.ResponseWriter, req *http.Request) {
		startReq := &start{}
		if err := json.NewDecoder(req.Body).Decode(startReq); err != nil {
			http.Error(w, err.Error(), http.StatusBadRequest)
			return
		}

		f, err := os.OpenFile(startReq.File, os.O_RDONLY, 0o600)
		if err != nil {
			http.Error(w, err.Error(), http.StatusInternalServerError)
			return
		}

		// Close the file immediately, this allows us to test what happens in the daemon when the plugin has closed the
		// file or, for example, the plugin has crashed.
		f.Close()

		w.WriteHeader(http.StatusOK)
		fmt.Fprintln(w, `{}`)
	})
	server := http.Server{
		Addr:              l.Addr().String(),
		Handler:           mux,
		ReadHeaderTimeout: 2 * time.Second, // This server is not for production code; picked an arbitrary timeout to statisfy gosec (G112: Potential Slowloris Attack)
	}

	server.Serve(l)
}
