Functions

func New

func New(opts ...cache.Option) (cache.RawCache, error)

New creates a new Valkey cache.

Types

type Cache

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

Cache is a JetStream-backed cache implementation using the NATS KeyValue store.

func (*Cache) Close

func (vc *Cache) Close() error

Close closes the Valkey connection.

func (*Cache) Decrement

func (vc *Cache) Decrement(ctx context.Context, key string, delta int64) (int64, error)

Decrement atomically decrements a counter.

func (*Cache) Delete

func (vc *Cache) Delete(_ context.Context, key string) error

Delete removes an item from the cache.

func (*Cache) Exists

func (vc *Cache) Exists(_ context.Context, key string) (bool, error)

Exists checks if a key exists in the cache.

func (*Cache) Expire

func (vc *Cache) Expire(_ context.Context, _ string, _ time.Duration) error

Expire updates the TTL of an existing key. JetStream KV TTL is configured at bucket level, so per-key TTL changes are not supported.

func (*Cache) Flush

func (vc *Cache) Flush(_ context.Context) error

Flush clears all items from the cache.

func (*Cache) Get

func (vc *Cache) Get(_ context.Context, key string) ([]byte, bool, error)

Get retrieves an item from the cache.

func (*Cache) Increment

func (vc *Cache) Increment(_ context.Context, key string, delta int64) (int64, error)

Increment atomically increments a counter.

func (*Cache) Set

func (vc *Cache) Set(_ context.Context, key string, value []byte, _ time.Duration) error

Set sets an item in the cache with the specified TTL.

func (*Cache) SupportsPerKeyTTL

func (vc *Cache) SupportsPerKeyTTL() bool
