Types ¶

type Cache ¶

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

Cache is a simple map cache that stores values in memory. It is safe for concurrent use.

func New ¶

func New[K Key, V Value](opts Opts) *Cache[K, V]

New initializes a Cache. The minimum size is 1024. cleanerInterval specifies the interval that Cache scans and discards expired values. If cleanerInterval <= 0, a default interval will be used.

func (*Cache[K, V]) Close ¶

func (c *Cache[K, V]) Close() error

Close closes the inner cleaner of this cache.

func (*Cache[K, V]) Flush ¶

func (c *Cache[K, V]) Flush()

Flush removes all stored entries from this cache.

func (*Cache[K, V]) Get ¶

func (c *Cache[K, V]) Get(key K) (v V, expirationTime time.Time, ok bool)

func (*Cache[K, V]) Len ¶

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

Len returns the current size of this cache.

func (*Cache[K, V]) Range ¶

func (c *Cache[K, V]) Range(f func(key K, v V, expirationTime time.Time) error) error

Range calls f through all entries. If f returns an error, the same error will be returned by Range.

func (*Cache[K, V]) Store ¶

func (c *Cache[K, V]) Store(key K, v V, expirationTime time.Time)

Store stores this kv in cache. If expirationTime is before time.Now(), Store is an noop.

type Key ¶

type Key interface {
	concurrent_lru.Hashable
}

type Opts ¶

type Opts struct {
	Size            int
	CleanerInterval time.Duration
}

type Value ¶

type Value interface {
	any
}
