下面的例子获得了一个python Decimal class 的reference。· // Equivalent to "from decimal import Decimal" py::object Decimal = py::module::import("decimal").attr("Decimal"); // Try to import scipy py::object scipy = py::module::import("scipy"); return scipy.attr("__version__"); ...
absl::StatusOrobjects must be returned by value (not reference or pointer). Why? Because the implementation takes advantage of the fact that python is a dynamically typed language to cast and return the payloadortheabsl::Statusobject (or raise an exeception). Python has no concept of aabsl...
使用方法,类似这样:m.def("get_data", &get_data, py::return_value_policy::reference);以Python对象作为参数Dictvoid print_dict(const py::dict& dict) { /* Easily interact with Python types */ for (auto item : dict) std::cout << "key=" << std::string(py::str(item.first)) << "...

don’t think too much. But it could be very confusing, if you give more thought to it.
you have full access to the object state and you could pass it in the lambda you are using for the __setstate__ function and return a reference to this, right? Or if that still doesn't work, you could just define __setstate__ yourself, although it would be really brittle due to ...
