Function dumps 

pub fn dumps<'py>(
    object: &Bound<'py, PyAny>,
    version: i32,
) -> Result<Bound<'py, PyBytes>, PyErr>

Available on crate feature tls and non-Py_LIMITED_API only.

Serialize an object to bytes using the Python built-in marshal module.

The built-in marshalling only supports a limited range of objects. The exact types supported depend on the version argument. The VERSION constant holds the highest version currently supported.

See the Python documentation for more details.

Examples

let dict = PyDict::new(py);
dict.set_item("aap", "noot").unwrap();
dict.set_item("mies", "wim").unwrap();
dict.set_item("zus", "jet").unwrap();

let bytes = marshal::dumps(&dict, marshal::VERSION);
