类名称：Observable
方法名：concatMapSingleDelayError

Observable.concatMapSingleDelayError介绍

[英]Maps the upstream items into SingleSources and subscribes to them one after the other succeeds or fails, emits their success values and delays all errors till both this Observable and all inner SingleSources terminate.

Scheduler: concatMapSingleDelayError does not operate by default on a particular Scheduler.
[中]将上游项映射到单一源中，并一个接一个地订阅它们，发送它们的成功值，并延迟所有错误，直到可观察到的和所有内部单一源终止。
调度程序：默认情况下，concatMapSingleDelayError不会在特定调度程序上运行。
