Detailed Description

\rst This a move-only guard that redirects output.

.. code-block:: cpp

#include <pybind11/iostream.h>

...

{
    py::scoped_ostream_redirect output;
    std::cout << "Hello, World!"; // Python stdout
} // <-- return std::cout to normal

You can explicitly pass the c++ stream and the python object, for example to guard stderr instead.

.. code-block:: cpp

{
    py::scoped_ostream_redirect output{std::cerr, py::module::import("sys").attr("stderr")};
    std::cout << "Hello, World!";
}
