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