I probably didn't read what you have wrote in the first message carefuly
enough. Does it mean something like that will work
type SomeTypes interface {
type int, float32, float64
}
func Min[T SomeTypes](x, y T) T {
switch T {
case int:
if x < y {
return x
}
return y
case float32:
return math.Min(float64(x), float64(y))
case float64:
return math.Min(x, y)
}
}
Would something like below work as well?
type Compare[T any] interface {
Compare(x, y T) int
}
type CompareConstraints[T any] {
type int, int8, …, float64, string, Compare[T]
}
func Min[T CompareConstraints]Min(x, y T) bool {
switch T {
case int:
…
…
case Compare[T]:
return x.Compare(y) < 0
}
}
