Method: Guard.run_supervised_task

.run_supervised_task(guard, task, *args) ⇒ Object

Run a Guard task, but remove the Guard when his work leads to a system failure.

  • guard (Guard::Guard) —

    the Guard to execute

  • task (Symbol) —

    the task to run

  • args (Array) —

    the arguments for the task

Raises:

  • (:task_has_failed) —
