Overview
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
