Define map with struct as a key where struct has pointer(s) defined

[aamir (Aamir Zia)]

Hi Folks,
I am struggling to make a map work which has a struct as a key where the struct has a pointer.
e.g.

type Person struct{
name string
height *float64
}

height1 := float64(5.3)
height2 := float64(5.3)
p1:= &Person{name:“ab”, height:&height1}
p2:= &Person{name:“ab”, height:&height2}

myMap := map[Person]string{p1:“hello”}

if _, found := myMap[p2]; !found{
// above condition is true while p2 and p1 has exact same data but pointers to heights are different
}

What are my options to actually make such struct work as keys for map? In C# if you override equality operator on struct/class then things work just fine but I see no such option in Go language.
Any help will be appreciated.

thanks
Zia

You cannot. You could however create a string representation that you could use as the map key, or not use a pointer.
