// contains filtered or unexported fields
}
Implements a PriorityQueue

func NewPriorityQueue() *PriorityQueue
func (PriorityQueue) Len ¶
func (p PriorityQueue) Len() int
func (*PriorityQueue) Peek ¶
func (p *PriorityQueue) Peek() *PQItem
func (*PriorityQueue) Pop ¶
func (p *PriorityQueue) Pop() *PQItem
func (*PriorityQueue) Push ¶
func (p *PriorityQueue) Push(el *PQItem)
func (*PriorityQueue) Remove ¶
func (p *PriorityQueue) Remove(el *PQItem)
func (*PriorityQueue) Update ¶
func (p *PriorityQueue) Update(el *PQItem, priority int)
Modifies the priority and value of an Item in the queue.
type TTLMap ¶
type TTLMap struct {
// Optionally specifies a callback function to be
// executed when an entry has expired
OnExpire func(key string, i interface{})
// contains filtered or unexported fields
}
