std::mergeable(3)	       C++ Standard Libary	       std::mergeable(3)

NAME
     std::mergeable - std::mergeable

Synopsis
	Defined in header <iterator>
	template< class I1, class I2, class Out, class Comp = ranges::less,

		  class Proj1 = std::identity, class Proj2 = std::identity >
	concept mergeable =
	    std::input_iterator<I1> &&
	    std::input_iterator<I2> &&
	    std::weakly_incrementable<Out>				      &&
     (since C++20)
	    std::indirectly_copyable<I1, Out> &&
	    std::indirectly_copyable<I2, Out> &&
	    std::indirect_strict_weak_order<Comp,
					    std::projected<I1, Proj1>,

					    std::projected<I2, Proj2>>;

	The mergeable concept specifies the  requirements  for	algorithms  that
     merge two input
	ranges	into a single output range according to the strict weak ordering
     imposed by
	Comp.

	Semantic requirements

	mergeable is modeled only if all concepts it subsumes are modeled.
