Namespaces
namespace	ROOT
	tbb::task_arena is an alias of tbb::interface7::task_arena, which doesn't allow to forward declare tbb::task_arena without forward declaring tbb::interface7
namespace	ROOT::Internal
namespace	ROOT::Internal::RDF
namespace	ROOT::RDF

Typedefs
template<bool IsSingleColumn, typename Ret_t >
using	ROOT::Internal::RDF::ColumnType_t = typename ColumnType< Ret_t, IsSingleColumn >::type
	When varying a single column, Ret_t is RVec<T> and ColumnType_t is T.

Functions
Helper functions for the case of a single column being varied.
template<typename T >
void	ROOT::Internal::RDF::AssignResults (ROOT::RVec< T > &resStorage, ROOT::RVec< T > &&tmpResults)
	Assign into fLastResults[slot] without changing the addresses of its elements (we gave those addresses away in GetValuePtr) The callee is responsible of making sure that resStorage has the correct size.
template<typename T >
std::size_t	ROOT::Internal::RDF::GetNVariations (const RVec< T > &results)
template<typename T >
void *	ROOT::Internal::RDF::GetValuePtrHelper (ROOT::RVec< T > &v, std::size_t, std::size_t varIdx)
template<typename T >
void	ROOT::Internal::RDF::ResizeResults (ROOT::RVec< T > &results, std::size_t, std::size_t nVariations)
template<typename T >
bool	ROOT::Internal::RDF::ResultsSizeEq (const T &results, std::size_t expected, std::size_t nColumns, std::true_type)
Helper functions for the case of multiple columns being varied simultaneously.
