func New(de, ci time.Duration) *Cache func New(de, ci time.Duration) *Cache
Returns a new cache with a given default expiration duration and default cleanup Returns a new cache with a given default expiration duration and default cleanup
interval. If the expiration duration is less than 1, the items in the cache never interval. If the expiration duration is less than 1, the items in the cache never
expire and must be deleted manually. If the cleanup interval is less than one, expire and must be deleted manually. If the cleanup interval is less than one,
expired items are not deleted from the cache before their next lookup or before expired items are not deleted from the cache before their next lookup or before
calling DeleteExpired. calling DeleteExpired.
