* @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.
