select_all_biased

[kuviman]

Currently biased select is only available via macro select_biased!. It would be useful to also have fn select_biased_all with same logic

I'm not sure if you meant future::select_all or stream::select_all.

Well, im not exactly sure how select_biased works for streams, the docs only show a stream with s.next() call which is a future.

In case it does work for actual streams, stream::select_biased_all would probably make sense too, but i was speaking of just future::select_biased_all
