In DelayedJob we can use Delayed::Job.all
on console to list all jobs on queue.
Is there a way to do the same using SuckerPunch gem?
With SuckerPunch everything runs in-process, so there is no external job queue backed by a database or other data store that can be queried from a separate process.
The only way I can think of to achieve what you want is to attach to the running Ruby process via a debug session and examine memory to dump out the information you want.
Based on my knowledge of SuckerPunch, if examining the jobs from the console or other process is a feature you need, you will have to switch to some other background job framework.
