Scheduler

what library is it from?

How would you re-run it multiple times then? An internal should be progressively greater. How would you terminate it if it continues to produce an exception?

what if one of the calls crashes? how would you re-run it?

If you need for them to run at a specific time, spawn task ,tokio::time::sleep , run job, loop.

How would you do it every 30 minutes? Every 5 hours? Once a day?

For my project I just run them.

How would you “just run” a task every 30 minutes? Every 5 hours? Once a day?
