Types

type LRUCache

type LRUCache[K comparable, V any] struct {
	// contains filtered or unexported fields
}

LRUCache wraps hashicorp *lru.Cache and tracks cache metrics

func NewLRUCache

func NewLRUCache[K comparable, V any](m Metrics, label string, maxSize int) *LRUCache[K, V]

NewLRUCache creates a LRU cache with the given metrics, labeling the cache adds/gets. Metrics are optional: no metrics will be tracked if m == nil.

func (*LRUCache[K, V]) Add

func (c *LRUCache[K, V]) Add(key K, value V) (evicted bool)

func (*LRUCache[K, V]) Get

func (c *LRUCache[K, V]) Get(key K) (value V, ok bool)

type Metrics

type Metrics interface {
	CacheAdd(label string, cacheSize int, evicted bool)
	CacheGet(label string, hit bool)
}
