Resolving the eventloop.poll()

[Frantisekf]

Hi, I'm very very new to rust and MDNS stuff so I apologize for dumb questions. I stumbled upon this problem with service browsers, and that's how to actually break the poll loop and return the found services back to main method. the code is similar to the example for browsing

fn on_service_discovered(
    result: zeroconf::Result<ServiceDiscovery>,
    _context: Option<Arc<dyn Any>>,
) {
    let res = result.unwrap();

    let serialized = serde_json::to_string(&res).unwrap();
    println!("serialized = {}", serialized);
}

#[tokio::main]
async fn main() {
    // let services = RwLock::new(Vec::new());
    // listen(services.write()?);

    let mut browser = MdnsBrowser::new("_http._tcp");

    browser.set_service_discovered_callback(Box::new(on_service_discovered));    
    let event_loop = browser.browse_services().unwrap();

    loop {    
        event_loop.poll(Duration::from_secs(0)).result();
     }

It really depends on the design of your application but one way to do this would have a bool field in your context object and check that in the loop. The context could be updated in another thread or something when you want to shutdown.
