WebThe PYBIND11_MODULE () macro creates a function that will be called when an import statement is issued from within Python. The module name ( example ) is given as the first macro argument (it should not be in quotes). The second argument ( m) defines a variable of type py::module_ which is the main interface for creating bindings. Webpybind11 uses C++11 move constructors and move assignment operators whenever possible to efficiently transfer custom data types. It's easy to expose the internal storage of custom data types through Pythons' buffer protocols. This is handy e.g. for fast conversion between C++ matrix classes like Eigen and NumPy without expensive copy operations. sons of anarchy opie kills stahl
