Parameters
| sender | - | input sender of which the stopped channel is mapped into err

Return value
Returns a sender which completes when the provided sender completes and sends values equivalent to those of the provided sender
Notes
- Once
ensure_startedreturns, it is known that the provided sender has been connected and start has been called on the resulting operation state. In other words, the work described by the provided sender
- If the returned sender is destroyed before execution::connect() is called, or if execution::connect() is called but the returned operation-state is destroyed before execution::start()
- In such a case, the operation's result will be discarded when it is eventually complete.
- Note that the application will need to make sure that resources are kept alive in the case that the operation detaches (e.g. by holding a std::shared_ptr
