Gautham, I think you might be misunderstanding how the Maybe<> API is supposed to be used. When used correctly, it is absolutely safe and will never crash.
- Maybe::FromJust() / MaybeLocal::ToLocalChecked() are intended for when you know for sure that the Maybe / MaybeLocal is not empty. Usually, the only case when you would know that is when you've just checked. - Maybe::IsNothing() / Maybe::IsJust() / MaybeLocal::IsEmpty() are intended for doing precisely that check. Typical usage looks like: MaybeLocal<Value> result = ...; if (result.IsEmpty()) { // Handle error case, e.g. print a warning. return false; } else { // .ToLocalChecked is safe to use here :-) do_something_with(result.ToLocalChecked()); } For convenience, there are also the Maybe::FromMaybe() / MaybeLocal::ToLocal() helpers: Maybe<int> maybe_x = ...; int x = maybe_x.FromMaybe(-1); // same as: // int x = maybe_x.IsJust() ? maybe_x.FromJust() : -1; Of course you can also use Private Symbols if you prefer; but there's really no reason to avoid private fields for stability reasons.
