Struct PyAttributeError 

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

Represents Python’s AttributeError exception.

Example: Raising AttributeError from Rust

This exception can be sent to Python code by converting it into a PyErr, where Python code can then catch it.

use pyo3::prelude::*;
use pyo3::exceptions::PyAttributeError;

#[pyfunction]
fn always_throws() -> PyResult<()> {
    let message = "I'm AttributeError, and I was raised from Rust.";
    Err(PyAttributeError::new_err(message))
}

Python code:

from my_module import always_throws

try:
   always_throws()
except AttributeError as e:
   print(f"Caught an exception: {e}")

Example: Catching AttributeError in Rust

use pyo3::prelude::*;
use pyo3::exceptions::PyAttributeError;
use pyo3::ffi::c_str;

Python::attach(|py| {
    let result: PyResult<()> = py.run(c_str!("raise AttributeError"), None, None);

    let error_type = match result {
        Ok(_) => "Not an error",
        Err(error) if error.is_instance_of::<PyAttributeError>(py) => "AttributeError",
        Err(_) => "Some other error",
    };

    assert_eq!(error_type, "AttributeError");
});
