         Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

   next
         my $doc = $cursor->next;

       Fetch next document. You can also append a callback to perform operation non-blocking.

         $cursor->next(sub {
           my ($cursor, $err, $doc) = @_;
           ...
         });

         });
