1.  class JRateLimiter extends ThreadSafeRateLimiter

   Java-friendly version of ThreadSafeRateLimiter.

2.  trait LimitCallback[T <: AnyRef] extends AnyRef

   Used by JRateLimiter in lieu of call-by-name from java.

3.  class RateLimiter extends AnyRef

   Used to rate-limit calls to a work function, e.g.

   Used to rate-limit calls to a work function, e.g. that writes to a db.

   Note you can disable the rate limiter by setting the frequency to 0.

   The math is as follows (mod some conversions between seconds and nano-seconds):

   After n samples, we can computer Ri as the "immediate rate" like:

   Ri = (n-1) / (timestamp(n) - timestamp(0))

   which is essentially the 1/average interval.

   Given a target rate, Rt ("maxFreqHz"), we can compute it like:

   Rt = n / (S + (timestamp(n) - timestamp(0))

   S here is how long to sleep before we invoke the next operation. Solving for S:

   S = n / Rt - (timestamp(n) - timestamp(0))

4.  class SingletonCache[K] extends AnyRef

   For objects that need their lifecycle to be managed and can't be just throw-away.

   For objects that need their lifecycle to be managed and can't be just throw-away. E.g. for when ConcurrentHashMap.putIfAbsent(new Something()) may result in a Something instance that need to be closed if another thread's putIfAbsent was successful.

   In this case it's easier to not create unnecessary instances in the first place.

5.  class ThreadSafeRateLimiter extends RateLimiter

   Fairly heavy-handed thread safe version of the above.

   Fairly heavy-handed thread safe version of the above. There's not a lot of point to trying to avoid locking here, since the whole point of this thing is to block writes, so we might as well keep it simple.

6.  trait VersionUtil extends AnyRef

   Used to get hold of the version of a particular item in the manifest.

7.  trait ExponentialBackoff extends AnyRef

   To avoid tight loops around errors.

   To avoid tight loops around errors.
