type RestConnection added in v0.12.0 

type RestConnection struct {
	BaseConnection   `mapstructure:",squash"`
	Endpoint         string `mapstructure:"endpoint" validate:"required" json:"endpoint"`
	Proxy            string `mapstructure:"proxy" json:"proxy"`

type WorkerScheduler 

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

WorkerScheduler runs asynchronous tasks in parallel with throttling support

func NewWorkerScheduler 

func NewWorkerScheduler(
	ctx context.Context,
	workerNum int,
	maxWork int,
	maxWorkDuration time.Duration,
	maxRetry int,
	logger core.Logger,
) (*WorkerScheduler, error)

NewWorkerScheduler creates a WorkerScheduler

func (*WorkerScheduler) HasError added in v0.12.0 

func (s *WorkerScheduler) HasError() bool

HasError return if any error occurred

func (*WorkerScheduler) NextTick added in v0.12.0 

func (s *WorkerScheduler) NextTick(task func() error)

NextTick enqueues task in a NonBlocking manner, you should only call this method within task submitted by SubmitBlocking method IMPORTANT: do NOT call this method with a huge number of tasks, it is likely to eat up all available memory

func (*WorkerScheduler) Release 

func (s *WorkerScheduler) Release()

Release resources

func (*WorkerScheduler) SubmitBlocking added in v0.12.0 

func (s *WorkerScheduler) SubmitBlocking(task func() error)

SubmitBlocking enqueues a async task to ants, the task will be executed in future when timing is right. It doesn't return error because it wouldn't be any when with a Blocking semantic, returned error does nothing but causing confusion, more often, people thought it is returned by the task. Since it is async task, the callframes would not be available for production mode, you can export Environment Varaible ASYNC_CF=true to enable callframes capturing when debugging. IMPORTANT: do NOT call SubmitBlocking inside the async task, it is likely to cause a deadlock, call SubmitNonBlocking instead when number of tasks is relatively small.

func (*WorkerScheduler) Wait added in v0.12.0 

func (s *WorkerScheduler) Wait() error

Wait blocks current go-routine until all workers returned
