The built in flow DSL.

Halting

Steps can be halted, which will stop the flow from continuing and return a halted flow. To attach a specific reason, use a halt_reason. If you need more complex halting logic, then you'd want to use a custom step, and return {:error, Ash.Error.Flow.Halted.exception(...)}
