Struct cpython::NoArgs

pub struct NoArgs;

An empty struct that represents the empty argument list. Corresponds to the empty tuple () in Python.

Example

let gil_guard = cpython::Python::acquire_gil();
let py = gil_guard.python();
let os = py.import("os").unwrap();
let pid = os.call(py, "getpid", cpython::NoArgs, None).unwrap();

Trait Implementations

impl Clone for NoArgs

fn clone(&self) -> NoArgs

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for NoArgs

impl Debug for NoArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'s> FromPyObject<'s> for NoArgs

fn extract(py: Python<'_>, obj: &'s PyObject) -> PyResult<Self>

Returns Ok(NoArgs) if the input is an empty Python tuple. Otherwise, returns an error.

impl ToPyObject for NoArgs

Converts NoArgs to an empty Python tuple.

type ObjectType = PyTuple

fn to_py_object(&self, py: Python<'_>) -> PyTuple

Converts self into a Python object.

fn into_py_object(self, py: Python<'_>) -> Self::ObjectType where
    Self: Sized, 

Converts self into a Python object.

fn with_borrowed_ptr<F, R>(&self, py: Python<'_>, f: F) -> R where
    F: FnOnce(*mut PyObject) -> R, 

Converts self into a Python object and calls the specified closure on the native FFI pointer underlying the Python object.
