module Freno
class Throttler
# An Instrumenter is an object that responds to
# `instrument(event_name, payload = {})` to receive events from the
# throttler.
#
# As an example, in a rails app one could use ActiveSupport::Notifications
# as an instrumenter and subscribe to the "freno.*" events somewhere else in
# the application.
#
module Instrumenter
# The Noop instrumenter is the `:instrumenter` used by default in the
# Throttler
#
# It does nothing but yielding the control to the block given if it is
# provided.
