mixedPackHelper()

template<typename BufferIter , typename BufferType , typename ValueType >

mixedPackSizeHelper() [1/2]

template<typename BufferType >

constexpr std::size_t RayTracingPackingUtils::detail::mixedPackSizeHelper ( const std::size_t  offset, const std::size_t  size  )

constexpr

Helper for mixedPackSize().

Called after evaluating the last InputType, and increases the size if any offset remains

Definition at line 114 of file RayTracingPackingUtils.h.

{
  return offset ? size + 1 : size;
}

mixedPackSizeHelper() [2/2]

template<typename BufferType , typename InputType , typename... Rest>

constexpr std::size_t RayTracingPackingUtils::detail::mixedPackSizeHelper ( std::size_t  offset, std::size_t  size  )

constexpr

Recursive helper for mixedPackSize().

Recurses through the types (in InputType and rest), and increments the offset and size as needed

Definition at line 127 of file RayTracingPackingUtils.h.

{
  return offset + sizeof(InputType) > sizeof(BufferType)
             ? mixedPackSizeHelper<BufferType, Rest...>(sizeof(InputType), ++size)
             : mixedPackSizeHelper<BufferType, Rest...>(offset + sizeof(InputType), size);

void RayTracingPackingUtils::detail::mixedUnpackHelper	(	BufferIter &	in,
		const BufferType *&	src,
		std::size_t &	src_offset,
		ValueType &	output
	)

Helper for mixedUnpack()
