custom handler?

func ExampleServer() {
s, err := socks5.NewClassicServer("127.0.0.1:1080", "127.0.0.1", "", "", 0, 60)
if err != nil {
log.Println(err)
return
}
// You can pass in custom Handler
s.ListenAndServe(nil)
// #Output:
}

I'm new, can you give an example or clarification in passing a custom Handler?

I came here looking for the same thing. I want to redirect custom traffic over Tor but I don't understand how to set up this scenario.
