Example for an empty stream for stubbing

[ydirson]

I'm working on a project where I use async_stream for interfacing with an optional crate. I wish to propose a stub for platforms that don't have support for this crate.

The following naive attempt does not work (the compiler tells me I'd rather use unit type as return value), likely because the lack of a yield does not allow the macro to derive an iterm type:

    pub fn stream(&mut self) -> impl Stream<Item = io::Result<NetEvent>> + '_ {
        try_stream! {
        }
    }

How can I achieve that ?

You can use futures::stream::empty::<io::Result<NetEvent>>()

That works great, thanks!
Maybe a note about this case and this solution could fit in the doc ?
