* @brief Register the type T for direct serialization within Boost.MPI | |
* | |
* The @c register_serialized function registers a C++ type for direct | |
* serialization within Boost.MPI. Direct serialization elides the use | |
* of the Python @c pickle package when serializing Python objects | |
* that represent C++ values. Direct serialization can be beneficial | |
* both to improve serialization performance (Python pickling can be | |
* very inefficient) and to permit serialization for Python-wrapped | |
* C++ objects that do not support pickling. | |
* | |
* @param value A sample value of the type @c T. This may be used | |
* to compute the Python type associated with the C++ type @c T. | |
* | |
* @param type The Python type associated with the C++ type @c | |
* T. If not provided, it will be computed from the same value @p | |
* value. | |
