Struct cpython::PyModule

pub struct PyModule(/* private fields */);

Represents a Python module object.

Implementations

impl PyModule

pub fn new(py: Python<'_>, name: &str) -> PyResult<PyModule>

Create a new module object with the __name__ attribute set to name.

pub fn import(py: Python<'_>, name: &str) -> PyResult<PyModule>

Import the Python module with the specified name.

pub fn dict(&self, py: Python<'_>) -> PyDict

Return the dictionary object that implements module’s namespace; this object is the same as the __dict__ attribute of the module object.

pub fn name<'a>(&'a self, py: Python<'_>) -> PyResult<&'a str>

Gets the module name.

May fail if the module does not have a __name__ attribute.

pub fn filename(&self, py: Python<'_>) -> PyResult<&str>

Gets the module filename.

May fail if the module does not have a __file__ attribute.

pub fn filename_object(&self, py: Python<'_>) -> PyResult<PyObject>

Gets the module filename object.

May fail if the module does not have a __file__ attribute.

pub fn get(&self, py: Python<'_>, name: &str) -> PyResult<PyObject>

Gets a member from the module. This is equivalent to the Python expression: getattr(module, name)

pub fn call<A>( &self, py: Python<'_>, name: &str, args: A, kwargs: Option<&PyDict> ) -> PyResult<PyObject>

where A: ToPyObject<ObjectType = PyTuple>,

Calls a function in the module. This is equivalent to the Python expression: getattr(module, name)(*args, **kwargs)

args should be a value that, when converted to Python, results in a tuple. For this purpose, you can use:

• cpython::NoArgs when calling a method without any arguments
• otherwise, a Rust tuple with 1 or more elements

Example

use cpython::NoArgs;
let sys = py.import("sys").unwrap();
// Call function without arguments:
let encoding = sys.call(py, "getdefaultencoding", NoArgs, None).unwrap();
// Call function with a single argument:
sys.call(py, "setrecursionlimit", (1000,), None).unwrap();

pub fn add<V>(&self, py: Python<'_>, name: &str, value: V) -> PyResult<()>

where V: ToPyObject,

Adds a member to the module.

This is a convenience function which can be used from the module’s initialization function.

pub fn add_class<T>(&self, py: Python<'_>) -> PyResult<()>

where T: PythonObjectFromPyClassMacro,

Adds a new extension type to the module.

This is a convenience function that initializes the py_class!(), sets new_type.__module__ to this module’s name, and adds the type to this module.

Trait Implementations

impl<'s> FromPyObject<'s> for &'s PyModule

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

Extracts Self from the source PyObject.

impl<'s> FromPyObject<'s> for PyModule

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

Extracts Self from the source PyObject.

impl PythonObject for PyModule

unsafe fn unchecked_downcast_from(obj: PyObject) -> Self

Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.

unsafe fn unchecked_downcast_borrow_from<'a>(obj: &'a PyObject) -> &'a Self

Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.

fn as_object(&self) -> &PyObject

Casts the Python object to PyObject.

fn into_object(self) -> PyObject

Casts the Python object to PyObject.

impl PythonObjectWithCheckedDowncast for PyModule

fn downcast_from<'p>( py: Python<'p>, obj: PyObject ) -> Result<PyModule, PythonObjectDowncastError<'p>>

Cast from PyObject to a concrete Python object type.

fn downcast_borrow_from<'a, 'p>( py: Python<'p>, obj: &'a PyObject ) -> Result<&'a PyModule, PythonObjectDowncastError<'p>>

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for PyModule

fn type_object(py: Python<'_>) -> PyType

Retrieves the type object for this Python object type.

impl ToPyObject for PyModule

Identity conversion: allows using existing PyObject instances where T: ToPyObject is expected.

type ObjectType = PyModule

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

Converts self into a Python object.

fn into_py_object(self, _py: Python<'_>) -> PyModule

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.
