    .and_then(move |c| c.query_all("SELECT * FROM person"))
    .and_then(|(block, _)| {
        for row in 0 .. block.row_count() {
            let id: u32    = block.get(row, "person_id")?;
            let name: &str = block.get(row, "name")?;

        }
        Ok(())
    })
    .map_err(|err| println!("database error: {}", err));

tokio::run(done)
