Struct pyo3::types::PyAny

#[repr(transparent)]
pub struct PyAny(_);

Represents a python's Any type. We can convert all python objects as PyAny.

In addition, if the inner object is an instance of type T, we can downcast PyAny into T.

Example

use pyo3::prelude::*;
use pyo3::types::{PyAny, PyDict, PyList};
let gil = Python::acquire_gil();
let dict = PyDict::new(gil.python());
assert!(gil.python().is_instance::<PyAny, _>(dict).unwrap());
let any = dict.as_ref();
assert!(any.downcast_ref::<PyDict>().is_ok());
assert!(any.downcast_ref::<PyList>().is_err());

Methods
