Types

type Cache

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

Cache represents a cache manager.

func New

func New[K comparable, V any](ttl time.Duration) *Cache[K, V]

New creates a new cache manager.

func (*Cache[K, V]) Delete

func (a *Cache[K, V]) Delete(key K)

Delete deletes the value for a key.

func (*Cache[K, V]) Len

func (a *Cache[K, V]) Len() int

Len returns the cache length.

func (*Cache[K, V]) Load

func (a *Cache[K, V]) Load(key K) (value V, ok bool)

Load returns the value stored in the cache for a key, or zero value if no value is present. The ok result indicates whether value was found in the cache.

func (*Cache[K, V]) LoadAndDelete

func (a *Cache[K, V]) LoadAndDelete(key K) (value V, loaded bool)

LoadAndDelete deletes the value for a key, returning the previous value if any. The loaded result reports whether the key was present.

func (*Cache[K, V]) LoadOrStore

func (a *Cache[K, V]) LoadOrStore(key K, value V) (actual V, loaded bool)

LoadOrStore returns the value by key, if not exist, puts value in the key, and returns it. The loaded result is true if the value was loaded, false if stored.

func (*Cache[K, V]) Range

func (a *Cache[K, V]) Range(f func(key K, value V) bool)

Range calls f sequentially for each key and value present in the cache. If f returns false, range stops the iteration.

func (*Cache[K, V]) Store

func (a *Cache[K, V]) Store(key K, value V)

Store sets the value for a key.
