Is it possible to await for interests on *multiple* AsyncFd?

[lestrozi]

Hello
I have multiple sockets open and I want to read UDP packets from any of them.
A simple way to do that is to create one task per socket and socket[i].readable().await on each of them, but I'm wondering if it is possible to create a single task that register Interest::READABLE on all my sockets and gets awaken when any become readable?

Thanks!

You can do that with tokio::join! and other similar utilities in the futures crate, but spawning separate tasks will often perform better.

AFAIK join! will only return when all tasks are done, not when any. Did I get this wrong?

Right, I meant select.
