Is there a way to recover from ensure blocks in the raise dsl?

Well, recover exists. But likely you want to use any of the myriad of other builders to recover.

My intuition would be to do something like

ensure(...) {
  recover {
    // ...
  }
}

[Carter Hudson]

but that’s probably not right

[Youssef Shoaib [MOD]]

Oh, I see you. I mean, you can do non-local returns inside ensure, so you could do something like:

someFunction {
  ensure(...) { return@someFunction ... }
}

But at this point, why not just use if(!condition) ...

I have a case where I want to ensure a locally stored value isn’t null, but if it is, I want to invoke a function that fetches it remotely and proceeds 🤔

[Youssef Shoaib [MOD]]

That's just ?: lol
I think you could be experiencing a golden hammer problem?

[Carter Hudson]

Entirely possible

[Carter Hudson]

I’m simplifying things a bit for the sake of an example, but it’s entirely possible I’m overthinking it

[Youssef Shoaib [MOD]]

Not intending any disrespect or anything of course to be clear, just saying that I think it's good to thing of ensure as if (!condition) raise(block() and hence if you want "variations" on it, you likely want an if statement

No worries; thanks for the advice
