Method instance

src/err.rs:385–391

Retrieves the exception instance for this error. This method takes `&mut self` because the error might need to be normalized in order to create the exception instance.

(&mut self, py: Python)

    /// This method takes `&mut self` because the error might need
    /// to be normalized in order to create the exception instance.
    pub fn instance(&mut self, py: Python) -> PyObject {
        self.normalize(py);
        match self.pvalue {
            Some(ref instance) => instance.clone_ref(py),
            None => py.None(),
        }
    }

    /// Writes the error back to the Python interpreter's global state.
    /// This is the opposite of `PyErr::fetch()`.
