Examples

See examples/.

The following sends three messages, transforms them, and prints the results:

cargo run --example send | cargo run --example echo_upper | cargo run --example recv

This example would read messages from STDIN and echos them back to STDOUT:

async fn echo() -> Result<(), io::Error> {
    let stdin = io::stdin().lock().await;
    let stdout = io::stdout().lock().await;
    let mut reader = Reader::new(stdin);
    let mut writer = Writer::new(stdout);
    while let Some(msg) = reader.next().await {
        let msg = msg?;
        writer.send(msg).await?;
    }
    Ok(())
}
