select_all() or race_all()?

[Josh Junon]

The futures package has a select_all() function that races a collection of futures and returns the first resolved future's index without dropping the rest.

Is there a way to do this in async-std? I'd rather not pull in the entirety of futures just for one function call 😅 I see there's a .race() method somewhere but it's not immediately clear on how to use it for something like this, or if it will drop the "losing" future.

Thanks for any information!

Thanks for asking; that's a good question! We're working on new versions of these operations in the futures-concurrency crate, with an eye of creating primitives which we put up for inclusion in the stdlib as well. Once we're happy with the design the plan is to re-export them from async-std. Until then I can recommend using those operations directly from the futures-concurrency crate.

I hope that answers your question!

So to be clear, futures-concurrency has candidate members that will ultimately be exposed directly from async-std in the future, right?

[Yosh]

That's the goal, indeed.

Cool! Thanks :)
