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?

The readme for smol has an example for stdout. I assume stdin is the same:

        let mut stdout = Unblock::new(std::io::stdout());
        io::copy(stream, &mut stdout).await?;

And there is more information about how to use it for reading/writing on the Unblock docs.

Oh yeah, the docs even mention Unblock<Stdin> explicitely. Thanks a lot!
