Enum cpython_json::JsonError

pub enum JsonError {
    PythonError(PyErr),
    SerdeJsonError(Error),
    TypeError(String, PyResult<String>),
    DictKeyNotString(PyObject),
    InvalidFloat,
    ImpossibleNumber,
}

The Error enum returned by this crate.

Most of the time you will just want a PyErr, and to_pyerr will convert to one for you.

Variants

PythonError(PyErr)

A Python exception occurred.

SerdeJsonError(Error)

The PyObject passed could not be converted to a serde_json::Value because of a serde_json error.

TypeError(String, PyResult<String>)

The PyObject passed could not be converted to a serde_json::Value object because we didn't recognize it as a valid JSON-supported type.

The error tuple is the type name, then the repr of the object.

This usually means that Python's json module wouldn't be able to serialize the object either. If the Python json module works but cpython-json doesn't, please [file an issue] (https://github.com/ilianaw/rust-cpython-json/issues) with your test case.

DictKeyNotString(PyObject)

A dict key was not a string object, and so it couldn't be converted to an object. JSON object keys must always be strings.

InvalidFloat

A number provided is not a valid JSON float (infinite and NaN values are not supported in JSON).

ImpossibleNumber

The serde_json crate lied to us and a Number is neither u64, i64, or f64.

Methods

impl JsonError

pub fn to_pyerr(&self, py: Python) -> PyErr

Convenience method for converting a JsonError to a PyErr.

Trait Implementations

impl Debug for JsonError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for JsonError

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for JsonError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.

impl From<PyErr> for JsonError

fn from(err: PyErr) -> JsonError

Performs the conversion.

impl From<Error> for JsonError

fn from(err: Error) -> JsonError

Performs the conversion.
