+    '''A class for asynchronously iterating values in a queue and waiting
+    for the queue to be updated with new values through a callback function.
+
+    An instance is an async iterator which for every iteration waits for
+    callbacks to add values to the queue and then returns it.
+
+    :Parameters:
+
+        `filter`: callable or None
+            A callable that is called with :meth:`callback`'s positional
+            arguments. When provided, if it returns false, this call is dropped.
+        `convert`: callable or None
+            A callable that is called with :meth:`callback`'s positional
+            arguments. It is called immediately as opposed to async.
+            If provided, the return value of convert is returned by
+            the iterator rather than the original value. Helpful
+            for callback values that need to be processed immediately.
+        `maxlen`: int or None
+            If None, the callback queue may grow to an arbitrary length.
+            Otherwise, it is bounded to maxlen. Once it's full, when new items
+            are added a corresponding number of oldest items are discarded.
+        `thread_fn`: callable or None
+            If reading from the queue is done with a different thread than
+            writing it, this is the callback that schedules in the read thread.
