Error: TypeError: 'Kind' object cannot be converted to 'Kind'

Complex type conversion seems to go wrong.

Error: TypeError: 'Kind' object cannot be converted to 'Kind'

Rust :

#[pyclass]
#[derive(Debug, Clone, PartialEq, EnumString, Display, Serialize, Deserialize)]
#[strum(serialize_all = "lowercase")]
#[serde(rename_all = "lowercase")]
pub enum Kind {
    Spot,
    Contract,
}

Python :

call() -> List[Tuple[Kind, str, Decimal, Decimal, Decimal]]:
    result = []
    result.append((Kind.Spot,'', Decimal(0), Decimal(0), Decimal(0)))
    result

Call :

let result = result.as_ref(py).extract()?;

The type I want to get

Vec<(Kind, String, Decimal, Decimal, Decimal)>

Could you post the full compilerinterpreter output. Usually such errors indicate that you use Kind instances from two different PyO3-based extensions. (Due to static linking, they do not share types even if their Rust implementations do, i.e. Kind from one extension has a different type than the Kind from the other.)

Could you post the full ~compiler~interpreter output. Usually such errors indicate that you use Kind instance from two different PyO3-based extensions.

Export enum as python class via pyo3. Then use rust to call the python function, and the enum(Kind.Spot) returned by python cannot be converted to Rust enum(Kind::Spot) through extract. Tip: 'Kind' object cannot be converted to 'Kind'

Without a full minimal reproduction this just sounds like you're running up against #1444

Thanks, I probably got it. Types in static libraries are not the same as types from Rust sources.
