Struct dataCache

balancer/rls/cache.go:166–178

dataCache contains a cache of RLS data used by the LB policy to make routing decisions. The dataCache will be keyed by the request's path and keys, represented by the `cacheKey` type. It will maintain the cache keys in an `lru` and the cache data, represented by the `cacheEntry` type, in a native m
