 2. Use the library in you project:

+   This library is async and built on [tokio](https://tokio.rs); add it to your
+   own `[dependencies]` (e.g. `tokio = { version = "1", features =
+   ["rt-multi-thread", "macros"] }`) to run the example below.
+
   ```rust
   use r701::R701;
+   use tokio_stream::StreamExt;

-   fn main() {
-       let mut r701 = R701::connect("127.0.0.1:5005").unwrap();
+   #[tokio::main]
+   async fn main() {
+       let mut r701 = R701::connect("127.0.0.1:5005").await.unwrap();

-       println!("No\tMchn\tEnNo\t\tName\t\tMode\tIOMd\tDateTime\t");
-       r701.into_record_iter()
+       let records = r701
+           .into_record_iter()
+           .await
           .unwrap()
           .collect::<Vec<_>>()
-           .iter()
-           .rev()
-           .enumerate()
-           .for_each(|(id, record)| {
-               let name = r701
-                   .get_name(record.employee_id)
-                   .unwrap()
-                   .unwrap_or(format!("user #{}", record.employee_id));
+           .await;

-               println!(
-                   "{:0>6}\t{}\t{:0>9}\t{: <10}\t{}\t{}\t{}",
-                   id + 1,
-                   1,
-                   record.employee_id,
-                   name,
-                   35,
-                   record.clock as u8,
-                   record.datetime.format("%Y/%m/%d  %H:%M:%S"),
-               );
-           });
+       println!("No\tMchn\tEnNo\t\tName\t\tMode\tIOMd\tDateTime\t");
+       for (id, record) in records.iter().rev().enumerate() {
+           let record = record.as_ref().unwrap();
+           let name = r701
+               .get_name(record.employee_id)
+               .await
+               .unwrap()
+               .unwrap_or(format!("user #{}", record.employee_id));
