Types ¶

type Cache ¶

type Cache struct {
	// contains filtered or unexported fields
}

Cache is a high-performance sharded LRU byte cache. It provides O(1) lookups with minimal lock contention.

func New ¶

func New(maxBytes int) *Cache

New creates a new byte cache with the given max size in bytes.

func (*Cache) Del ¶

func (c *Cache) Del(key []byte)

Del removes a key from the cache.

func (*Cache) Get ¶

func (c *Cache) Get(dst, key []byte) []byte

Get looks up a value by key, copying into dst if provided.

func (*Cache) GetBig ¶

func (c *Cache) GetBig(dst, key []byte) []byte

GetBig is an alias for Get (compatibility).

func (*Cache) Has ¶

func (c *Cache) Has(key []byte) bool

Has reports whether a key exists.

func (*Cache) HasGet ¶

func (c *Cache) HasGet(dst, key []byte) ([]byte, bool)

HasGet returns the value and whether it exists.

func (*Cache) LoadFromFile ¶

func (c *Cache) LoadFromFile(filePath string) error

LoadFromFile is a no-op for compatibility with fastcache API.

func (*Cache) Reset ¶

func (c *Cache) Reset()

Reset clears all cached entries.

func (*Cache) SaveToFileConcurrent ¶

func (c *Cache) SaveToFileConcurrent(filePath string, concurrency int) error

SaveToFileConcurrent is a no-op for compatibility with fastcache API.

func (*Cache) Set ¶

func (c *Cache) Set(key, value []byte)

Set stores a key/value pair.

func (*Cache) SetBig ¶

func (c *Cache) SetBig(key, value []byte)

SetBig is an alias for Set (compatibility).

func (*Cache) UpdateStats ¶

func (c *Cache) UpdateStats(s *Stats)

UpdateStats populates the provided stats struct.

type Stats ¶

type Stats struct {
	EntriesCount uint64
	BytesSize    uint64
	Collisions   uint64
	GetCalls     uint64
	SetCalls     uint64
	Misses       uint64
}

Stats contains cache performance metrics.
