You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: custom_options.rb
    path of file: ./repos/gitlabhq/lib/gitlab/lograge
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  mod
    
      def self.call(event)
        params = event
          .payload[:params]
          .each_with_object([]) { |(k, v), array| array << { key: k, value: v } unless IGNORE_PARAMS.include?(k) }
        payload = {
          time: Time.now.utc.iso8601(3),
          params: Gitlab::Utils::LogLimitedArray.log_limited_array(params, sentinel: LIMITED_ARRAY_SENTINEL)
        }

        payload.merge!(event.payload[:metadata]) if event.payload[:metadata]
        optional_payload_params = event.payload.slice(*KNOWN_PAYLOAD_PARAMS).compact
        payload.merge!(optional_payload_params)

        ::Gitlab::InstrumentationHelper.add_instrumentation_data(payload)

        payload[Labkit::Correlation::CorrelationId::LOG_KEY] = event.payload[Labkit::Correlation::CorrelationId::LOG_KEY] || Labkit::Correlation::CorrelationId.current_id

        # https://github.com/roidrage/lograge#logging-errors--exceptions
        exception = event.payload[:exception_object]

        ::Gitlab::ExceptionLogFormatter.format!(exception, payload)

        if Feature.enabled?(:feature_flag_state_logs)
          payload[:feature_flag_states] = Feature.logged_states.map { |key, state| "#{key}:#{state ? 1 : 0}" }
        end
