Function statistic_from_pyobject 

pub fn statistic_from_pyobject(
    py: Python<'_>,
    statistic: Py<PyAny>,
) -> PyResult<Statistic>

Converts statistic into a registrable Statistic.

A built-in statistic type converts to its native Rust implementation, keeping calculation in Rust. Any other object is wrapped as a PythonStatistic and dispatched back into Python on calculation, including a user-defined class whose name matches a built-in.

Errors

Returns an error if the object’s class cannot be resolved, or if a user-defined statistic has no name attribute resolving to a non-empty string.
