The rationale for this is that it is more flexible for use cases when `Stream<Item = Result<T, Error>>`.

Take for example `tokio_stream::Broadcast` then one would have to something like:

```rust
   let stream = BroadcastStream::new(rx).take_while(|r| future::ready(r.is_ok())).filter_map(|r| future::ready(r.ok()));
```

Of course it's a bit awkward to return `Result` when the underlying stream can't fail but I think that's fair trade-off
here.
