When it comes time to actually document code for public consumption, Rust's missing_docs lint is great. I don't have to search out every place that needs documentation; I can just let the compiler yell at me about it.
In related news, Effectum first release is basically done. All the basic tests are there and I got a big performance improvement by batching database operations together, so it can process about 50,000 do-nothing jobs per second on my laptop. Going to clean some things up and then the first actual release should come early next week.
Some future features will include auto-recurring jobs, the ability to cancel or modify jobs that haven't started running yet, and support for running the task queue as its own server.
