  • What's this?

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
