Marker interface for caches backed by durable storage (disk, database). Mirrors SwiftyNetwork's PersistentCache.

Inheritors

Functions

A hot stream of CacheChanges for this cache. The default is an empty flow, so caches that cannot observe mutations are simply non-reactive; observable caches override this.

entry

open suspend fun entry(key: CacheKey): CacheEntry<V>?

Atomically returns the value and its timestamp for key, or null if absent.

removeAll

abstract suspend fun removeAll()

Removes every entry.

removeValue

abstract suspend fun removeValue(key: CacheKey)

Removes any value stored for key.

setValue

abstract suspend fun setValue(value: V, key: CacheKey)

Stores value for key, stamping it with the current time.

timestamp

abstract suspend fun timestamp(key: CacheKey): Long?

Returns the epoch-millisecond timestamp recorded for key, or null if absent.

value

abstract suspend fun value(key: CacheKey): V?

Returns the value stored for key, or null if absent.
