A Handle is used to record the start and finish time of event.

Both start and finish must each be called exactly once.

Where possible, it’s best to use the block form: ActiveSupport::Notifications.instrument. Handle is a low-level API intended for cases where the block form can’t be used.

handle = ActiveSupport::Notifications.instrumenter.build_handle("my.event", {})
begin
  handle.start
  # work to be instrumented
ensure
  handle.finish
end
