Examples

To[int] example.

valInt, err := cast.To[int]("56")
// or valPtrInt, err := To[*int]("56")
if err != nil {
	panic(err)
}

To[time.Time] example (supports strings only in time.RFC3339).

valTime, err := cast.To[time.Time]("2024-05-22T11:36:57+03:00")
// or valPtrTime, err := To[*time.Time]("2024-05-22T11:36:57+03:00")
if err != nil {
	panic(err)
}

ToReflect(string, reflect.Type) example.

timeType := reflect.TypeOf(time.Time{})
valTime, err := cast.ToReflect("2024-05-22T11:36:57+03:00", timeType)
// or valPtrTime, err := ToReflect("2024-05-22T11:36:57+03:00", reflect.PointerTo(timeType))
if err != nil {
	panic(err)
}

ToFrom(string, any) example.

date := time.Time{}
err := cast.ToFrom("2024-05-22T11:36:57+03:00", &date)
if err != nil {
	panic(err)
}
