Get list of queued items in AsyncQueue

[n9]

Is your feature request related to a problem? Please describe.

I want to get an ordered list of queued items in AsyncQueue.

Describe the solution you'd like

I would be nice to have a method that would return the ordered list of queued items.

Describe alternatives you've considered

I have not found any public members that can be used to achieve that.

Can you share your scenario that would need such an API? The primary use case for this class does not require this.

[n9]

Sure. My scenario is following:

I am using it for a very simple task queue.
I/users would like to see what items/tasks are waiting.

(I know that there is currently no update information.)

[AArnott]

Thanks. And would Queue<T> or List<T> make an adequate substitute for your use case?

[n9]

I do not want to block a thread while waiting for a new task. The task queue is empty most of the time. Tasks are queued only occasionally.

[AArnott]

The work may not be trivial, given exposing the inner collection would introduce a thread-safety problem so we would likely need to copy the collection within a lock and then return it. I can't promise a timeline or whether we'll get to this feature request at this point.

I have mocked a PR: #987.
