cuda::experimental::stf::tuple_transform

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.
