store v8::Local in std containers like vector, unordered_map

[dark...@gmail.com]

I have code like:

v8::Isolate::Scope isolate_scope(isolate);
v8::HandleScope handle_scope(isolate);

v8::Local<v8::Context> context = v8::Context::New(isolate);
v8::Context::Scope context_scope(isolate);

{
  std::vector<v8::Local<v8::Object> > ret = some_func();

  some_another_func(ret);

}

Is this code valid if container lifetime < lifetime of handle_scope? Is normal to store v8::Local in heap (like std containers do)?

You'll want to put it in a global, not a local.   Globals outlive their lexical scope.

Just as a note, they're move-only.

I believe that should work as long as you respect the lifetimes, yes.

Oops, I didn't look closely enough at your example.   What ben said.

But if you want to store them longer, then you'll want the global..
