Instance Method Details

#call ⇒ Object

Registers an at_exit callback, which checks if there was an exception. This is a pretty crude way to detect exceptions from runner commands, but Rails doesn't provide a better API.

This should only be called from a runner callback in your Rails config; otherwise you may register the at_exit callback in more places than you need or want it.
