async fn main() {
    // Graylog address
    let address = "127.0.0.1:12201";

    // Initialize subscriber
    let conn_handle = Logger::builder().init_tcp(address).unwrap();

    // Spawn background task
    // Any futures executor can be used
    tokio::spawn(conn_handle.connect());

    // Send a log to Graylog
    tracing::info!(message = "oooh, what's in here?");

    // Create a span
    let span = tracing::info_span!("cave");
    span.in_scope(|| {
        let test = tracing::info_span!("deeper in cave", smell = "damp");
        test.in_scope(|| {
            // Send a log to Graylog, inside a nested span
            tracing::warn!(message = "oh god, it's dark in here");
        })
