| Eagerly starts a sender, returning a sender that will deliver the results to a receiver to which it is connected and started, if any. When the result sender is not connected to a receiver, or if the resulting operation state is not started, the results are ignored. If such a sender is destroyed before the underlying operation completes, the operation continues running detached. (function template) |
