Question

http://play.golang.org/p/joEmjQdMaS

    field         


        

Answer 1

package main

import (
    "fmt"
)


type SomeTest struct {
    someVal string
}

func (this *SomeTest) String() string {
    return this.someVal
}

func main() {
    fmt.Println(&SomeTest{"You can see this now"})
}

Anything that provides the Stringer interface will be printed with it's String() method. To implement stringer, you only need to implement String() string. To do what you want, you'd have to implement Stringer for SomeStruct (in your case, dereference somePointer and do something with that).
