NumberSetIterator

public struct NumberSetIterator<T> : IteratorProtocol where T : FixedWidthInteger, T : UnsignedInteger

An Iterator that return the elements of a NumberSet.

  • The elements returned by the NumberSetIterator are of type Int.

    Declaration

    Swift

    public typealias Element = Int

  • Creates a new iterator from the specified value.

    Declaration

    Swift

    public init(rawValue: T)

    Parameters

    rawValue

    An unsigned FixedWidhtInteger with a bit represeting each element that will be returned by the iterator.

  • Advances to the next element and returns it, or nil if no next element exists.

    The next element returned is represented by the lowest bit that is set and is cleared before returning. Once all of the bits are clear then all subsequent calls return nil.

    Declaration

    Swift

    public mutating func next() -> Element?
