Constructor Details

#initialize(config_entries:, entry_count:) ⇒ DescribeConfigsReport

Returns a new instance of DescribeConfigsReport.

Parameters:

  • config_entries (FFI::Pointer) —

    pointer to the event-owned config entries array. It is only read here - the array is destroyed together with the result event by the background event callback, so this report must be built while the event is alive and must copy everything it needs into Ruby objects.

  • entry_count (Integer) —

    number of config entries
