But look at what libc++’s own documentation says about the current state. The default hardening mode is none. You have to opt into it. The “fast” mode suitable for production only checks two assertion categories: valid-element-access and valid-input-range. Iterator bounds checking requires ABI changes that most vendors haven’t enabled. The unordered containers (unordered_map, unordered_set, etc.) are only partially hardened. vector iterators aren’t hardened at all. And checking for iterator invalidation — accessing a vector element through an iterator after the vector has been reallocated — still leads to undefined behavior even with hardening enabled.
If you do the above, it will of course consume your Bar(s), but since this goes over the boundary you get no help from the compiler about how you manage the JS side! The object will get freed on the Rust side, but you still have a JS handle that now points to nothing. You might say something like “so much for memory safety”, and you wouldn’t be wrong.
