Function create_hashes

pub fn create_hashes<'a>(
    arrays: &[Arc<dyn Array>],
    random_state: &RandomState,
    hashes_buffer: &'a mut Vec<u64>,
) -> Result<&'a mut Vec<u64>, DataFusionError>

Creates hash values for every row, based on the values in the columns.

The number of rows to hash is determined by hashes_buffer.len(). hashes_buffer should be pre-sized appropriately
