A JVM in Rust part 5 – Executing instructions

  A tiny JVM written in Rust. Learning project

Your understanding of Rust is correct, but the code uses unsafe: https://github.com/andreabergia/rjvm/blob/93e7e48db085e780b0...

As a result, when the VM gets dropped, the memory gets deallocated even if there are still objects that reference it.

Why would they? The direction for safer JVM research is to implement JVMs in Java, which has the advantage of being both memory safe outside a few tiny core areas (same as rust) whilst having cleaner code than the Rust impl (none of these problems with lifetimes).
