While the
kv_def
macro was there previously, we did not use it in some placesbecause of the need for custom prefixes. This PR augments the
kv_def
andstring_kv_def
macros to take an optional string literal to be used as thePREFIX_CACHE
constant for theCacheKey
trait.Additionally this replaces the two manual implementations of the cache traits
with this new macro syntax.
