HandletimeFilter

A com.twitter.finagle.Filter that records the elapsed execution times of the underlying com.twitter.finagle.Service. Durations are recorded in microseconds and emitted as a stat labeled "handletime_us" to the argument com.twitter.finagle.stats.StatsReceiver.

Note: the stat does not include the time that it takes to satisfy the returned Future, only how long it takes for the Service to return the Future.

SimpleFilter[Req, Rep], Filter[Req, Rep, Req, Rep], (Req, Service[Req, Rep]) ⇒ Future[Rep], AnyRef, Any

Conditionally propagates requests down the filter chain.
