Types

type Executor

type Executor interface {
	ExecuteTask(ctx context.Context, pid peer.ID, task *peertask.Task) bool
}

Executor runs a single task on the queue

type TaskQueue

type TaskQueue interface {
	PushTask(p peer.ID, task peertask.Task)
	TaskDone(p peer.ID, task *peertask.Task)
	Remove(t peertask.Topic, p peer.ID)
	Stats() graphsync.RequestStats
}

type WorkerTaskQueue

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

TaskQueue is a wrapper around peertaskqueue.PeerTaskQueue that manages running workers that pop tasks and execute them

func NewTaskQueue

func NewTaskQueue(ctx context.Context) *WorkerTaskQueue

NewTaskQueue initializes a new queue

func (*WorkerTaskQueue) PushTask

func (tq *WorkerTaskQueue) PushTask(p peer.ID, task peertask.Task)

PushTask pushes a new task on to the queue

func (*WorkerTaskQueue) Remove

func (tq *WorkerTaskQueue) Remove(topic peertask.Topic, p peer.ID)

Remove removes a task from the execution queue

func (*WorkerTaskQueue) Shutdown

func (tq *WorkerTaskQueue) Shutdown()

Shutdown shuts down all running workers

func (*WorkerTaskQueue) Startup

func (tq *WorkerTaskQueue) Startup(workerCount uint64, executor Executor)

Startup runs the given number of task workers with the given executor

func (*WorkerTaskQueue) Stats

func (tq *WorkerTaskQueue) Stats() graphsync.RequestStats

Stats returns statistics about a task queue

func (*WorkerTaskQueue) TaskDone

func (tq *WorkerTaskQueue) TaskDone(p peer.ID, task *peertask.Task)

TaskDone marks a task as completed so further tasks can be executed
