            Move-assign a experimental::basic_concurrent_channel from
            another.
          
basic_concurrent_channel & operator=( basic_concurrent_channel && other);
This assignment operator moves a channel from one object to another. Cancels any outstanding asynchronous operations associated with the target object.
                  The other experimental::basic_concurrent_channel
                  object from which the move will occur.
                
            Following the move, the moved-from object is in the same state as if
            constructed using the basic_concurrent_channel(const executor_type&)
            constructor.
