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 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.
