I’ve built a rust library that interfaces directly with v8. I only have a high level idea of how this would work with elixir at the moment but my thought process is that the rust library will use rustler as the interface between rust and elixir and the rust code will spawn a separate thread that will contain the isolate, apply seccomp filters, etc.
Normally, the recommendation with v8 isolates is to run them in a separate OS process because v8 isolates can be hacked and a sandbox escape can expose shared memory.
