Variables

var NewExtension func(ctx context.Context, next TaskServiceExt, req *task.CreateTaskRequest) (TaskServiceExt, error)

NewExtension registers an extension constructor. It may return nil, nil to indicate that the extension should not handle this task request. Returning an error will fail the task request.
