I'm trying to set struct.field = &otherStruct. However, I have to use reflection, and otherStruct is of type interface{}.
The error I'm getting is:
reflect.Set: value of type main.StructB is not assignable to type *main.StructB
struct is known. The (real) type of otherStruct is not known, but it is guaranteed, that the assignment is safe (the struct type is identical).
Code:
type StrucA struct {
Field *StrucB
}
type StrucB struct {}
func main() {
a := StrucA{}
var b interface{} = StrucB{}
//above is set
// Target: Set a.Field = &b
reflect.ValueOf(&a).Elem().FieldByName("Field").Set(reflect.ValueOf(b)) // reflect.Set: value of type main.StrucB is not assignable to type *main.StrucB
}

I have tested a lot of different stuff, but I'm unable to solve it.
