pub struct PyAssertionError(/* private fields */);
Expand description
Represents Python’s AssertionError
exception.
§Example: Raising AssertionError 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::PyAssertionError;
#[pyfunction]
fn always_throws() -> PyResult<()> {
let message = "I'm AssertionError, and I was raised from Rust.";
Err(PyAssertionError::new_err(message))
}
Python code:
from my_module import always_throws
try:
always_throws()
except AssertionError as e:
print(f"Caught an exception: {e}")
§Example: Catching AssertionError in Rust
use pyo3::prelude::*;
use pyo3::exceptions::PyAssertionError;
use pyo3::ffi::c_str;
Python::attach(|py| {
let result: PyResult<()> = py.run(c_str!("raise AssertionError"), None, None);
let error_type = match result {
Ok(_) => "Not an error",
Err(error) if error.is_instance_of::<PyAssertionError>(py) => "AssertionError",
Err(_) => "Some other error",
};
assert_eq!(error_type, "AssertionError");
});
