TYPES
type Cache struct {
// contains filtered or unexported fields
}
func New() (c *Cache)
Create a new DB
func (c *Cache) Close()
Unset DB After this call, all methods will be invalid
func (c *Cache) Del(k string)
Delete k from db
func (c *Cache) Exists(k string) bool
Test if k exists in db
func (c *Cache) Flush()
Flush all keys
* design considerations:
best effort is made to reduce the gc cycle by manually close all the keys
that are going to be deleted or replaced but doing a loop or making a
storage for stopping all the timers are not worth the gain so they are
spared when flushing
func (c *Cache) Get(k string) interface{}
Get value from k return nil if the key is not set
func (c *Cache) Keys() (keys []string)
Return all keys *unsorted*
func (c *Cache) Set(k string, v interface{}, ttl ...int64)
Set k with v with an optional ttl in seconds
