if I have a long running task which I'm collecting with
```longRunningTask().collect{
   // ...
}```
is there a way of canceling in the middle of the collecting? Like: I wan the function to finish itself and stop doing what it was doing

You could consider using `transformWhile` which lets you return `true` or `false` to indicate whether you want to continue collecting the flow

I’m not sure why `collectWhile` (which exists) isn’t a public function :thinking_face: but `transformWhile { … }.collect()` achieves the same thing

from what you suggested, looking at the docs, we have `takeWhile`

what type* does `longRunningTask` return?

sometimes I'm lazy to explain things, my bad

since the condition in my case is to check whether a new message arrived in a channel, `channel.isEmpty()` , the `takeWhile{ channel.isEmpty }`  seems to be working
