Downstreaming changes to wasi:io/poll proposed here:
https://github.com/WebAssembly/wasi-io/pull/54poll-list becomes poll and poll-one becomes a method directly on pollable - these are NFCs, just renamings for ergonomics, and because poll-one was easily confused with poll-oneoff.
pollable.ready is new functionality that allows you to check the readiness of a pollable without blocking. I took the most trivial path to implement it via futures::poll_immediate. I had to add a minor optimization to the clock deadline future so that we can test it by asserting
subscribe_duration(0).ready()andsubscribe_instant(now() - 1).ready()are true.

Could this perhaps be
matches!(..., Some(()))to emphasize this isn't accidentally throwing away a "real" result from the poll?

Ideally this method wouldn't be on this list since it shouldn't block, but I can also see how that complicates the implementation, so I'm fine either way

Agreed. The implementation, as it stands, shouldn't ever actually be Pending, and I think we will be able to keep an eye on that invariant going forwards.
