A rollback option for seq, compose, parallel series etc. #1773

Closed from-nibly closed 2 years ago

from-nibly commented 2 years ago

I actually haven't used this library before. I found it because I was looking for a utility to do async rollbacks.

Essentially I'm looking for something to behave similar to a transaction system in a database. Where if I do 6 parallel things and one of them fails I don't want to have "done" any of them.

I found this but it hasn't been touched since 2013? https://github.com/rossj/async-rollback

Are there any plans/is there any interest in adding a rollback system?

something like instead of passing a single function just pass two in an object or a tuple that would represent do, undo.

If any of the do's fail then run all the undo functions for all the do functions that were at least started?

This sounds cool, but also complicated and tricky. Would be a lot of work to build and maintain.
