Types ¶
type ConcurrentQueue ¶
type ConcurrentQueue struct {
// contains filtered or unexported fields
}
ConcurrentQueue is a concurrent-safe FIFO queue with unbounded capacity. Clients interact with the queue by pushing items into the in channel and popping items from the out channel. There is a goroutine that manages moving items from the in channel to the out channel in the correct order that must be started by calling Start().
func NewConcurrentQueue ¶
func NewConcurrentQueue(bufferSize int) *ConcurrentQueue
NewConcurrentQueue constructs a ConcurrentQueue. The bufferSize parameter is the capacity of the output channel. When the size of the queue is below this threshold, pushes do not incur the overhead of the less efficient overflow structure.
func (*ConcurrentQueue) ChanIn ¶
func (cq *ConcurrentQueue) ChanIn() chan<- interface{}
ChanIn returns a channel that can be used to push new items into the queue.
func (*ConcurrentQueue) ChanOut ¶
func (cq *ConcurrentQueue) ChanOut() <-chan interface{}
ChanOut returns a channel that can be used to pop items from the queue.
func (*ConcurrentQueue) Start ¶
func (cq *ConcurrentQueue) Start()
Start begins a goroutine that manages moving items from the in channel to the out channel. The queue tries to move items directly to the out channel minimize overhead, but if the out channel is full it pushes items to an overflow queue. This must be called before using the queue.
func (*ConcurrentQueue) Stop ¶
func (cq *ConcurrentQueue) Stop()
Stop ends the goroutine that moves items from the in channel to the out channel. This does not clear the queue state, so the queue can be restarted without dropping items.
