The broadcast Receiver doesn't have a Stream impl.

Solution

Implement Stream for broadcast::Receiver

This is probably going to require a merge master / update once #2007 lands.

Thanks 👍

[bIgBV]

I'll keep track of it and update this PR once that lands.

[carllerche]

Mind merging?

[bIgBV]

Done

I'm not entirely sure why the rustfmt job is failing, as running it locally doesn't show any changes.

[carllerche]

Because cargo fmt is broken :)

We should add a script in our repo to run fmt...

CI uses this: https://github.com/tokio-rs/tokio/blob/master/ci/azure-rustfmt.yml#L17

[carllerche]

Oh, could you add a test that goes via the Stream impl?

It mostly will be copying an existing test but then explicitly calling StreamExt::next.

Great work! Thanks
