Static Variables
static var allZeros: Self Required
The empty bitset.
Also the identity element for | and
^, and the fixed point for
&.
Declaration
staticvarallZeros:Self{get}
Instance Methods
func &(_:rhs:)
Required
Returns the intersection of bits set in lhs and rhs.
Complexity: O(1).
Declaration
func&(lhs:Self,rhs:Self) ->Self
func ^(_:rhs:)
Required
Returns the bits that are set in exactly one of lhs and rhs.
Complexity: O(1).
Declaration
func^(lhs:Self,rhs:Self) ->Self
func |(_:rhs:)
Required
Returns the union of bits set in lhs and rhs.
Complexity: O(1).
Declaration
func|(lhs:Self,rhs:Self) ->Self
prefix func ~(_:)
Required
Returns x ^ ~Self.allZeros.
Complexity: O(1).
Declaration
prefixfunc~(x:Self) ->Self
A set type with O(1) standard bitwise operators.
Each instance is a subset of
~Self.allZeros.Axioms, where
xis an instance ofSelf:x | Self.allZeros == xx ^ Self.allZeros == xx & Self.allZeros == .allZerosx & ~Self.allZeros == x~x == x ^ ~Self.allZeros
