# This Rubocop will check for using the return value of StatsD metric calls, which is deprecated.
# To check your codebase, use the following Rubocop invocation:
#
# rubocop --require `bundle show statsd-instrument`/lib/statsd/instrument/rubocop.rb \
# --only StatsD/MetricReturnValue
#
# This cop cannot autocorrect offenses. In production code, StatsD should be used in a fire-and-forget
# fashion. This means that you shouldn't rely on the return value. If you really need to access the
# emitted metrics, you can look into `capture_statsd_calls`
