Set

The element type of the option set.

To inherit all the default implementations from the OptionSet protocol, the Element type must be Self, the default.

The corresponding value of the raw type.

A new instance initialized with rawValue will be equivalent to this instance. For example:

enum PaperSize: String {
    case A4, A5, Letter, Legal
}

let selectedSize = PaperSize.Letter
print(selectedSize.rawValue)
// Prints "Letter"

print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!)
// Prints "true"

Creates a new option set from the given raw value.

This initializer always succeeds, even if the value passed as rawValue exceeds the static properties declared as part of the option set. This example creates an instance of ShippingOptions 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"

Creates an instance containing just e

The type of the elements of an array literal.

The raw type that can be used to represent all values of the conforming type.

Every distinct value of the conforming type has a corresponding unique value of the RawValue type, but there may be values of the RawValue type that don’t have a corresponding value of the conforming type.
