Function hashmap_from_pyobject_pyo3 

pub fn hashmap_from_pyobject_pyo3<K, V>(
    py: Python<'_>,
    value: &Bound<'_, PyAny>,
) -> PyResult<HashMap<K, V>>
where
    K: for<'py> FromPyObjectOwned<'py> + DeserializeOwned + Eq + Hash,
    V: for<'py> FromPyObjectOwned<'py> + DeserializeOwned,
    HashMap<K, V>: DeserializeOwned,

Convert a Python mapping to a HashMap using typed PyO3 objects when possible.

Falls back to the generic JSON bridge when the input is not a Python dict. Individual dict keys and values first try typed PyO3 extraction, then JSON/Serde extraction.

Errors

Returns an error if the Python object cannot be converted to the requested map type.
