Optional dependencies (logging)

quanta

Enable this feature to use quanta::Instant for some performance critical operations in the cache instead of std::time::Instant. As of v0.12.10, this feature will not make any noticeable performance difference, but in the future when cache metrics are added, it will be useful to have this feature enabled.

atomic64

This is an old feature and has no effect in v0.12.10 or newer. It is kept for backward compatibility and will be removed in v0.13.0.

unstable-debug-counters = future

This unstable feature adds GlobalDebugCounters::current function, which returns counters of internal object construction and destruction. It will have some performance impacts and is intended for debugging.
