Thanks, very interesting. He is right, the Rust borrow checker can not deal with arbitrary graphs and she added a memory management layer on top of the Rust one

Thanks, very interesting. He is right, the Rust borrow checker can not deal with arbitrary graphs and she added a memory management layer on top of the Rust one. However, you would have to do the same in C++. It is an interesting obervation. I spoke to Benedikt Meurer from the Google V8 team recently and he pointed out the same for Javascript Engines. If you do not have DAGs, Rust can‘t help you with safety. (at least it can not prevent use after free) I still like the whole ECS idea and it makes sense for me that using ECS in Rust will provide a performant and clean architecture.
