Instance Method Details

#child_rss_kb ⇒ Object

Positive type checks, not nil checks. EV-s5br / GH #1174: the nil_replacement mutator can swap a nil default into ‘false` (or some other non-typed value), and `nil?` then returns false, sending a missing method to the wrong receiver and crashing the parent worker. Asking the field explicitly whether it is the expected struct keeps the parent process alive and lets the mutation count as a measured (errored) result.
