Type Aliases

FFIResult

Convenience type for results passed through the FFI boundary. Since the DataFusionError enum is complex and little value is gained from creating a FFI safe variant of it, we convert errors to strings when passing results back. These are converted back and forth using the df_result, rresult, and rresult_return macros.
