Creates an empty option set.
init() This initializer creates an option set with a raw value of zero.
Creates an empty option set.
init() where Self.RawValue:FixedWidthIntegerThis initializer creates an option set with a raw value of zero.
import Swiftprotocol OptionSet : RawRepresentable, SetAlgebraA type that presents a mathematical set interface to a bit set.
protocol FixedWidthInteger : BinaryInteger, LosslessStringConvertible where Self.Magnitude : FixedWidthInteger, Self.Magnitude : UnsignedInteger, Self.Stride : FixedWidthInteger, Self.Stride : SignedIntegerAn integer type that uses a fixed size for every instance.
init() Creates an empty set.
mutating func formIntersection(_ other: Self) Removes all elements of this option set that are not also present in the given set.
mutating func formSymmetricDifference(_ other: Self) Replaces this set with a new set containing all elements contained in either this set or the given set, but not in both.
mutating func formUnion(_ other: Self) Inserts the elements of another set into this option set.
