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

Public Member Functions
constexpr	predicate () noexcept=default
	Initialize every logical lane to false.
constexpr	predicate (bool value) noexcept
	Broadcast the supplied truth value to every logical lane.
constexpr native_type	to_native () const noexcept
	Return the native storage representation.
constexpr std::uint64_t	to_bitset () const noexcept
	Pack lane truth into low bits, with lane zero in bit zero.
constexpr predicate &	operator&= (predicate b) noexcept
	Apply the corresponding lane-wise AND operation in place and return *this.
constexpr predicate &	operator|= (predicate b) noexcept
	Apply the corresponding lane-wise OR operation in place and return *this.
constexpr predicate &	operator^= (predicate b) noexcept
	Apply the corresponding lane-wise XOR operation in place and return *this.

Static Public Member Functions
static constexpr predicate	from_native (native_type value) noexcept
	Import compact mask bits and clear bits above the lane count.
static constexpr predicate	unsafe_from_native (native_type value) noexcept
	Import compact bits and clear bits above the lane count, just like from_native.
static constexpr predicate	from_bitset (std::uint64_t value) noexcept
	Import lane truth from the low logical-lane bits.

Friends
constexpr predicate	operator~ (predicate a) noexcept
	Invert each lane truth value, preserving the mask representation.
constexpr predicate	operator! (predicate a) noexcept
	Return the lane-wise logical complement, retaining this mask type.
constexpr predicate	operator& (predicate a, predicate b) noexcept
	Bitwise AND of corresponding lane representations.
constexpr predicate	operator| (predicate a, predicate b) noexcept
	Bitwise OR of corresponding lane representations.
constexpr predicate	operator^ (predicate a, predicate b) noexcept
	Bitwise XOR of corresponding lane representations.
constexpr predicate	operator== (predicate a, predicate b) noexcept
	Return a mask whose lanes are true where a == b holds.
constexpr predicate	operator!= (predicate a, predicate b) noexcept
	Return a mask whose lanes are true where a != b holds.
constexpr bool	any (predicate a) noexcept
	Return whether at least one logical lane is true.
constexpr bool	all (predicate a) noexcept
	Return whether every logical lane is true.
constexpr bool	none (predicate a) noexcept
	Return true exactly when no logical lane is true.
constexpr predicate	select (predicate p, predicate a, predicate b) noexcept
	Choose a in true lanes and b in false lanes; both values are already evaluated.

Detailed Description

template<std::size_t N, ::native::isa<> Arch>
requires (::native::avx512 <= Arch ) && ::native::detail::avx512_backend::predicate_shape<N>
struct native::predicate< N, Arch >

Compact comparison storage. Every import clears bits above the lane count, including the compatibility unsafe_from_native spelling.
