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

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.

[Carter Hudson]

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
