cuda::experimental::stf::tuple_transform

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

template<typename Tuple, typename F>
constexpr auto cuda::experimental::stf::tuple_transform(Tuple &&t, F &&f)

Applies a transformation to each element of a tuple, optionally passing the index.

Iterates over the elements of a tuple and applies the provided functor f to each element. If f is invocable with both the index and the element (f(index, element)), that form is used. Otherwise, it falls back to f(element). The index is a compile-time constant of type std::integral_constant<std::size_t, i>, where i is the index of the element in the tuple.

Template Parameters

  • Tuple – The type of the input tuple.

  • F – The type of the transformation functor.

Parameters

  • t – The input tuple to transform.

  • f – The transformation functor. Must be invocable with either f(element) or f(index, element).

Returns

A new tuple containing the results of applying f to each element of t.
