Overview ¶
Cache works as thread-safe least recently used (LRU) cache with expiring items on a given TTL span. The TTL gets automatically re-cycled on each Get() call, which permits to stay longer in the cache.

Types ¶
type Cache ¶
type Cache struct {
// Logger defaults to stderr and adds a prefix of "cache: "
Logger *log.Logger
// contains filtered or unexported fields
}
Cache holds all items and configuration.
func New ¶
New creates a new cache instance, taking a ttl and max number for the containing items.
ttl = Null | never expires [~100 years] max = 0 | fallback to default maxItems [64]
func (*Cache) Debug ¶
Debug toggles (enables/disables) debug output through Logger and returns either true if enabled or respectively false if disabled.
func (*Cache) Once ¶
Once adds new item to the cache that expires after the first cycle and gets no update on a Get call.
