Collaboration diagram for native::predicate< N, A >:

Public Member Functions
constexpr	predicate () noexcept=default
	Construct an empty mask.
constexpr	predicate (bool value) noexcept
	Broadcast one Boolean value to every logical lane.
constexpr native_type	to_native () const noexcept
	Return the compact implementation representation.
constexpr std::uint64_t	bits () const noexcept
	Return one bit per logical lane.
constexpr std::uint64_t	to_bitset () const noexcept
	Return the logical lane bitset.
constexpr predicate &	operator&= (predicate b) noexcept
	Intersect with another mask in place.
constexpr predicate &	operator\|= (predicate b) noexcept
	Unite with another mask in place.
constexpr predicate &	operator^= (predicate b) noexcept
	Toggle lanes present in another mask.

Static Public Member Functions
static constexpr predicate	from_bits (std::uint64_t bits) noexcept
	Read one bit per lane and clear bits above the logical lane count.
static constexpr predicate	from_bitset (std::uint64_t bits) noexcept
	Construct from the logical lane bitset.
static constexpr predicate	from_native (native_type bits) noexcept
	Adopt the compact representation, clearing unused bits.

Friends
constexpr bool	any (predicate p) noexcept
	Test whether any logical lane is set.
constexpr bool	all (predicate p) noexcept
	Test whether every logical lane is set.
constexpr bool	none (predicate p) noexcept
	Test whether every logical lane is clear.
constexpr predicate	operator~ (predicate p) noexcept
	Complement logical lanes, leaving padding clear.
constexpr predicate	operator! (predicate p) noexcept
	Complement each logical lane.
constexpr predicate	operator& (predicate a, predicate b) noexcept
	Intersect the logical lane masks.
constexpr predicate	operator\| (predicate a, predicate b) noexcept
	Unite the logical lane masks.
constexpr predicate	operator^ (predicate a, predicate b) noexcept
	Toggle lanes present in exactly one operand.
constexpr predicate	operator== (predicate a, predicate b) noexcept
	Mark lanes whose truth values agree.
constexpr predicate	operator!= (predicate a, predicate b) noexcept
	Mark lanes whose truth values differ.
constexpr predicate	select (predicate p, predicate a, predicate b) noexcept
	Choose each mask lane from a or b according to p.
