Functions

func CloneValue 

func CloneValue(src interface{}) interface{}

func CloneValueTo 

func CloneValueTo(dst interface{}, src interface{})

Deep copy value Usage^ 

type data struct {
	a string
	b string
	c []string
}
src := &data{
 "works1",
 "works2",
  []string{"a", "b"},
}
var dst data
CloneValueTo(&dst, src)
src.c = append(src.c, "c")
fmt.Println(src)
fmt.Println(dst)

So you can pass any type at run time as long as you're sure that source and destin are both of the same type, (and destin is a pointer to that type).
