Public Member Functions
constexpr	keep_first (std::ptrdiff_t n) noexcept
	Construct an eve::relative_conditional_expr that will keep the n first lanes.
template<typename V >
constexpr auto	else_ (V const &v) const
	Extends a conditional expression with an alternative value.
template<typename T >
as_logical_t< T >	mask (eve::as< T > tgt) const
	Computes the eve::logical_value associated to the current conditional.
template<typename T >
constexpr std::ptrdiff_t	count (eve::as< T > tgt) const
	Number of lanes to be left unmasked.
constexpr bool friend	operator== (keep_first const &, keep_first const &)=default
	Checks equality between two eve::keep_first instances.

Friends
std::ostream &	operator<< (std::ostream &os, keep_first const &c)
	Inserts a eve::keep_first conditional expression into a output stream.
