Example

1. echo hello

#[tokio::main]
async fn main() {
    use flatline::session::Session;
    use flatline::handshake::Config;
    use tokio::net::TcpStream;
    use flatline::session::Userauth;
    use flatline::channel::ExitStatus;
    let socket = TcpStream::connect("192.168.8.190:22").await.unwrap();
    let config = Config::deafult_with_behavior();
    let mut session = Session::handshake(config, socket).await.unwrap();

    let status = session.userauth_password("zhou", "123456").await.unwrap();

    assert!(matches!(status, Userauth::Success));

    let mut channel = session.channel_open_default().await.unwrap();
    channel.exec("echo \"hello\"").await.unwrap();
    loop {
        let msg = channel.recv().await.unwrap();
        match msg {
            flatline::channel::Message::Close => break,
            flatline::channel::Message::Eof => break,
            flatline::channel::Message::Stdout(data) => assert_eq!(data, b"hello\n"),
            flatline::channel::Message::Stderr(_) => unreachable!(),
            flatline::channel::Message::Exit(status) => assert!(matches!(status, ExitStatus::Normal(0))),
        }
    }
}
