std::mergeable - cppreference.com

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> &&
    std::indirectly_copyable<I1, Out> &&

                                    std::projected<I2, Proj2>>; (since C++20)

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.

[edit] Semantic requirements

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