yield_entire_stream!(stream)

[manuels]

Sometimes you want to yield all items of a stream and yield some additional elements afterwards.
Something like

#[async]
for item in stream_a {
    stream_yield!(item)
}

#[async]
for item in stream_b {
    stream_yield!(item)
}

stream_yield!(0u8);
Ok(())

I would like to propose to add an additional macro that transform the code above to

yield_entire_stream!(stream_a);
yield_entire_stream!(stream_b);

stream_yield!(0u8);
Ok(())

Although I am open to rename the macro ;)

In Python, this is done using the yield from ... syntax. I'd propose stream_yield_from!(stream_a) to match that.

@anthonyclays, great idea!
