            Move-assign a experimental::basic_channel from another.
          
basic_channel & operator=( basic_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_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_channel(const executor_type&)
            constructor.
