Discussion 議論
This initializer always succeeds, even if the value passed as raw exceeds the static properties declared as part of the option set. This example creates an instance of Shipping with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members.
let extraOptions = ShippingOptions(rawValue: 255)
print(extraOptions.isStrictSuperset(of: .all))
// Prints "true"
