## Example

```rust
fn main() -> io::Result<()> {
    // load ssl keys
    let mut builder = SslAcceptor::mozilla_intermediate(SslMethod::tls()).unwrap();
    builder.set_private_key_file("./examples/key.pem", SslFiletype::PEM).unwrap();
    builder.set_certificate_chain_file("./examples/cert.pem").unwrap();
    let acceptor = builder.build();

    let num = Arc::new(AtomicUsize::new(0));

    // bind socket address and start workers. By default server uses number of
    // available logical cpu as threads count. actix net start separate
    // instances of service pipeline in each worker.
    Server::build()
        .bind(
            // configure service pipeline
            "basic", "0.0.0.0:8443",
            move || {
                let num = num.clone();
                let acceptor = acceptor.clone();

                // service for converting incoming TcpStream to a SslStream<TcpStream>
                fn_service(move |stream: Io<tokio_tcp::TcpStream>| {
                    SslAcceptorExt::accept_async(&acceptor, stream.into_parts().0)
                        .map_err(|e| println!("Openssl error: {}", e))
                })
                // .and_then() combinator uses other service to convert incoming `Request` to a
                // `Response` and then uses that response as an input for next
                // service. in this case, on success we use `logger` service
                .and_then(fn_service(logger))
                // Next service counts number of connections
                .and_then(move |_| {
                    let num = num.fetch_add(1, Ordering::Relaxed);
                    println!("got ssl connection {:?}", num);
                    future::ok(())
                })
            },
        )?
        .run()
}
