Types ¶
type DownloadCache ¶
type DownloadCache struct {
// contains filtered or unexported fields
}
DownloadCache is a thread-safe LRU cache for download data (e.g. season pack zip/rar contents). Evicts least-recently-used entries when the entry count exceeds maxEntries.
func New ¶
func New(maxEntries int, maxItemSize int64) *DownloadCache
New creates a DownloadCache with the given limits.
func (*DownloadCache) Clear ¶
func (dc *DownloadCache) Clear()
Clear removes all cached data and resets the saturation guard.
func (*DownloadCache) Get ¶
func (dc *DownloadCache) Get(key string) ([]byte, bool)
Get retrieves cached data by key. Returns nil, false on miss.
func (*DownloadCache) Put ¶
func (dc *DownloadCache) Put(key string, data []byte, onSaturated func()) bool
Put stores data under key. Returns false (without storing) if the data exceeds maxItemSize or the cache is full and cannot evict. The onSaturated callback is called at most once per Clear cycle when the cache refuses to store an entry.
