检查恐慌而无法恢复 [英] Checking for panic without recovering from it

问题描述

在defer函数中，我想查看一次恢复调用是否会产生非零值（不恢复）

In a defer function, I want to see whether a call to recover would yield a non-nil value (without recovering)

有可能吗？

推荐答案

那不可能。您可能只是想重新恐慌，就像在其他语言中重新引发异常一样；

That exact thing isn't possible. You probably just want to re-panic, basically like re-throwing an exception in other languages;

        defer func() {
             if e := recover(); e != nil {
                 //log and so other stuff
                 panic(e)
             }
          }()
