基于Redis 的任务队列Bull -- （十四）completed

当 job 完成时，queue 会将它移动到 completed 或 failed 状态

然后会触发 local 的 completed / failed 状态

const handleCompleted = result => {
  return job.moveToCompleted(result, undefined, notFetch).then(jobData => {
    utils.emitSafe(this, 'completed', job, result, 'active');
    return jobData ? this.nextJobFromJobData(jobData[0], jobData[1]) : null;
  });
};

const handleFailed = err => {
  const error = err;
  return job.moveToFailed(err).then(jobData => {
    utils.emitSafe(this, 'failed', job, error, 'active');
    return jobData ? this.nextJobFromJobData(jobData[0], jobData[1]) : null;
  });
};

moveToCompleted 是将 job 移动到完成状态

首先会对 returnValu
