object Balance

Fan-out the stream to several streams. Each upstream element is emitted to the first available downstream consumer. It will not shutdown until the subscriptions for at least two downstream subscribers have been established.

Emits when any of the outputs stops backpressuring; emits the element to the first available output

Backpressures when all of the outputs backpressure

Completes when upstream completes

Cancels when If eagerCancel is enabled: when any downstream cancels; otherwise: when all downstreams cancel
