I try to follow https://github.com/notify-rs/notify/blob/main/examples/async_monitor.rs, but there are some blocking thread like futures::executor::block_on.

So I would like to use it without blocking execution.
tokio::task::spawn_blocking can be the solution ?

I try

 let (tx, mut rx) = tokio::sync::mpsc::channel(256);
  let config = Config::default().with_poll_interval(duration::from_secs(2));

    let mut watcher = PollWatcher::new(move |res| {
      tx.send(res);
     }, config,
    ).unwrap();
   watcher.watch(Path::new("myfolder"), RecursiveMode::nonRecursive).unwrap();

   tokio::task::spawn_blocking(move || {
        while let Ok(Ok(file)) = rx.reicv() {
          println!("File changed : {}", file); // Expected some logs here !
        }
   });

I can successfully start non blocking thread, but nothing is displayed, when folder is modified

SO what is wrong ?
