Struct PyCFunction 

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

Represents a builtin Python function object.

Values of this type are accessed via PyO3’s smart pointers, e.g. as Py<PyCFunction> or Bound<'py, PyCFunction>.

Implementations

impl PyCFunction

pub fn new_with_keywords<'py>( py: Python<'py>, fun: PyCFunctionWithKeywords, name: &'static CStr, doc: &'static CStr, module: Option<&Bound<'py, PyModule>>, ) -> PyResult<Bound<'py, Self>>

Create a new built-in function with keywords (*args and/or **kwargs).

To create name and doc static strings on Rust versions older than 1.77 (which added c““ literals), use the c_str! macro.

pub fn new<'py>( py: Python<'py>, fun: PyCFunction, name: &'static CStr, doc: &'static CStr, module: Option<&Bound<'py, PyModule>>, ) -> PyResult<Bound<'py, Self>>

Create a new built-in function which takes no arguments.

To create name and doc static strings on Rust versions older than 1.77 (which added c““ literals), use the c_str! macro.

pub fn new_closure<'py, F, R>( py: Python<'py>, name: Option<&'static CStr>, doc: Option<&'static CStr>, closure: F, ) -> PyResult<Bound<'py, Self>>

where F: Fn(&Bound<'_, PyTuple>, Option<&Bound<'_, PyDict>>) -> R + Send + 'static, for<'p> R: IntoPyCallbackOutput<'p, *mut PyObject>,

Create a new function from a closure.

Examples

Python::attach(|py| {
    let add_one = |args: &Bound<'_, PyTuple>, _kwargs: Option<&Bound<'_, PyDict>>| -> PyResult<_> {
        let i = args.extract::<(i64,)>()?.0;
        Ok(i+1)
    };
    let add_one = PyCFunction::new_closure(py, None, None, add_one).unwrap();
    py_run!(py, add_one, "assert add_one(42) == 43");
});

Trait Implementations

impl PyTypeInfo for PyCFunction

const NAME: &'static str = "PyCFunction"

👎Deprecated since 0.28.0:

prefer using ::type_object(py).name() to get the correct runtime value

Class name.

const MODULE: Option<&'static str>

👎Deprecated since 0.28.0:

prefer using ::type_object(py).module() to get the correct runtime value

Module name, if any.

const TYPE_HINT: PyStaticExpr

Provides the full python type as a type hint.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn is_type_of(obj: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

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

Returns the safe abstraction over the type object.

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
