cuda::experimental::stf::shuffled_array_tuple

Defined in include/cuda/experimental/__stf/utility/traits.cuh

template<typename ...DataTypes, typename ...ArgTypes>
auto cuda::experimental::stf::shuffled_array_tuple(ArgTypes... args)

Creates a tuple where each element is an std::array, constructed from the arguments provided.

This function constructs a tuple where each element is an array of a specific type. Each array in the tuple contains all the arguments of the corresponding type. The function checks at compile-time to ensure that each argument type is convertible to exactly one of the tuple’s element types, avoiding ambiguity or incompatible types.

Example usage:

auto result = shuffled_array_tuple<int, double, char>('a', 5, 6.0, 'b', 7);
// result is a tuple containing:
// std::array<int, 2> {5, 7},
// std::array<double, 1> {6.0},
// std::array<char, 2> {'a', 'b'}

Note

The function uses all_convertible internally to construct arrays for each data type in DataTypes.

Template Parameters

• DataTypes – The types of the arrays in the tuple. Each type corresponds to an array in the tuple.

• ArgTypes – Variadic template representing the types of the arguments.

Parameters

args – The arguments from which the arrays in the tuple are constructed. These can be in any order.

Returns

A tuple where each element is an array of one of the DataTypes, containing the respective convertible arguments.
