Go doesn't support templates or generics. There are three things you can do:

  • use non-empty interfaces where applicable
  • generate code with go generate
  • use interface{}:

    type GoTemp struct {
        a interface{}
    func (gt *GoTemp) foo(v interface{}) {
        // ...
    func foo2(v interface{}) {
        // ...
