Function mz_compute::render::reduce::evaluate_mfp_after

fn evaluate_mfp_after<'a, 'b>(
    mfp_after: &'a Option<SafeMfpPlan>,
    datums_local: &'b mut DatumVecBorrow<'a>,
    temp_storage: &'a RowArena,
    key_len: usize
) -> Option<Row>

Evaluates the fused MFP, if one exists, on a reconstructed DatumVecBorrow containing key and aggregate values, then returns a result Row or None if the MFP filters the result out.
