How to assign a function to a field within a struct via the struct's pointer-CodePudding

I am struggling to understand how I can write this appropriately, what is different about funcs that I cannot assign them to a field within a struct via the structs pointer?

I receive a s.Bar undefined (type any has no field or method Bar) however I can access f.Text after assignment just fine.

type test func()

func hi() {
    fmt.Println("i work")
}

type Foo struct {
    Text string
    Bar  test
}

func BigTest(s any) {
    f := s.(*Foo)
    f.Bar = hi
    f.Text = "something"
    fmt.Println(f.Text)
    s.Bar()
}

func main() {
    f := Foo{}
    BigTest(&f)
}

CodePudding user response：

You have to call f.Bar() not s.Bar() because s is type any, and f is the one you type asserted.
