ruby on rails - comparison of Sidekiq::SortedEntry with Sidekiq::SortedEntry failed -

i've written snippet below identify if potential job unique , if not, not run it. iterating on each job in scheduled queue , looking @ job's arguments passed through. dependent on arguments, can determine if unique:

job_exists = { :appointment => false }  sidekiq::scheduledset.new.sort.each |job|   case job['args'][0]   when 'appointment'     job_exists[:appointment] = true   end end 

and in next snippet of code, checks boolean value , if doesn't exist run it.

however, i've been getting error comparison of sidekiq::sortedentry sidekiq::sortedentry thrown line: sidekiq::scheduledset.new.sort.each |job|.

why line causing error thrown?

because sorting entire set in memory. don't that.
