pub fn data_to_pycapsule(py: Python<'_>, data: Data) -> Py<PyAny>Expand description
Creates a Python PyCapsule object containing a Rust Data instance.
This function takes ownership of the Data instance and encapsulates it within
a PyCapsule object, allowing the Rust data to be passed into the Python runtime.
§Capsule type contract
When conversion to DataFFI fails (e.g. for Data::Custom), this returns a
capsule containing a single Data value (no destructor). That capsule must
never be passed to drop_cvec_pycapsule, which expects a CVec and
would cause undefined behavior. Only capsules produced by code that creates
CVec (e.g. for capsule_to_list) may be passed to drop_cvec_pycapsule.
§Panics
This function panics if the PyCapsule creation fails, which may occur if
there are issues with memory allocation or if the Data instance cannot be
properly encapsulated.
