cache 
Thread-safe implementation of different cache algorithms in golang
go get git.sr.ht/~xn/cache
// example: LRU
lru := cache.NewLRU(1000)
lru.Set(1, 10)
If you need only specific cache algorithm, you can import it without additional dependencies:
go get git.sr.ht/~xn/cache/lfu
lfuCache := lfu.New(1000)
lfuCache.Set(1, 10)
