Replacing async_std by smol: What about stdin? (programming.dev)

For my library, I want to replace async_std by smol, since the former has been deprecated in favor of the latter. This is mostly just a simple translation (different module structure, names etc.), but what I don't know is how to replace async-std's stdin. Anybody got a hint on that?

I've not looked too much into it, but it seems AsyncRead/AsyncBufRead (through IoSafe) is implemented for stdin. So i think you should be able to use it like that.

    Yeah that looks fine, thanks! It would introduce a new dependency (async_io) though, so I might go with Unblock mentioned above. Let's see what happens when I try to make the switch :)

    (e) Ah I don't think this really works, I'd need to wrap it in an Async, but the docs explicitely mention not to use that with Stdin: https://docs.rs/smol/latest/smol/struct.Async.html#supported-types. Unblock it is then :)
