IMO a groups of constraints are horrible with interfaces
type CommonResponse(type E) interface {
GetError() E
}
type CommonError interface {
GetCode() int32
}
func IsOK(type R CommonResponse(E), E CommonError)(r R) bool {
switch r.GetError().GetCode() {
case 0, 200, 201:
return true
default:
return false
}
}
vs
constract CommmonResponse(R, E) {
R GetError() E
E GetCode() int32
}
func IsOK(type R, E CommonResponse)(r R) bool {
switch r.GetError().GetCode() {
case 0, 200, 201:
return true
default:
return false
}
}
That trickery with commas to express dependcy of types is hard
