type Queue ¶

type Queue struct {
	// contains filtered or unexported fields
}

Queue provides a best-effort durability, FIFO interface to the datastore for storing cids

Best-effort durability just means that cids in the process of being provided when a crash or shutdown occurs may be in the queue when the node is brought back online depending on whether the underlying datastore has synchronous or asynchronous writes.

func NewQueue(ctx context.Context, name string, ds datastore.Datastore) (*Queue, error)

func (q *Queue) Close() error

func (q *Queue) Dequeue() <-chan cid.Cid

func (q *Queue) Enqueue(cid cid.Cid) error
