std::unifor...it_generator(3) C++ Standard Libarystd::unifor...it_generator(3) NAME std::uniform_random_bit_generator - std::uniform_random_bit_generator Synopsis Defined in header <random> template <class G> concept uniform_random_bit_generator = std::invocable<G&> && std::unsigned_integral<std::invoke_result_t<G&>> && requires { (since C++20) { G::min() } -> std::same_as<std::invoke_result_t<G&>>; { G::max() } -> std::same_as<std::invoke_result_t<G&>>; requires std::bool_constant<(G::min() < G::max())>::value; }; The concept uniform_random_bit_generator<G> specifies that G is the type of a uniform random bit generator, that is, objects of type G is a func- tion object returning unsigned integer values such that each value in the range of possible results has (ideally) equal probability of being returned. Semantic requirements uniform_random_bit_generator<G> is modeled only if, given any object g of type G: * g() is in the range [G::min(), G::max()] * g() has amortized constant complexity. Notes In order to satisfy the requirement std::bool_constant<(G::min() < G::max())>::value, both G::min() and G::max() must be constant ex- pressions, and the result of the comparison must be true. http://cppreference.com 2022.07.31 std::unifor...it_generator(3)
