cuda::experimental::stf::tuple2tuple

template<typename Tuple, typename Fun>
constexpr auto cuda::experimental::stf::tuple2tuple(

const Tuple &t,

Fun &&f

)

Converts each element in t to a new value by calling f, then returns a tuple collecting the values thus obtained.

  auto t  = ::std::make_tuple(1, 2, 3);
  auto t1 = tuple2tuple(t, [](auto x) {
    return x + 1.0;
  });
  static_assert(::std::is_same_v<decltype(t1), ::std::tuple<double, double, double>>);
  EXPECT(t1 == ::std::make_tuple(2.0, 3.0, 4.0));

Template Parameters:

• Tuple – Type of the tuple to convert

• Fun – Type of mapping function to apply

Parameters:

• t – Object to convert, must support std::apply

• f – function to convert each element of the tuple, must take a single parameter

Returns:

auto The tuple resulting from the mapping
