https://coredumped.dev/2022/04/11/implementing-a-safe-garbage-collector-in-rust/ · In my last post I introduced an Emacs Lisp VM I was writing in Rust. My stated goal at the time was to complete a garbage collector. I think Rust has some really interesting properties that will make building garbage collectors easier and safer. Many of the techniques used in my GC are not original and have been developed by other Rustaceans in previous projects. Why use garbage collection? virtually all non-trivial programs need some way to reuse memory.
