I'm not sure if I understand it correctly. So, if I have a hashtable, adding or removing an element would invalidate existing pointers to any other element in the hashtable? I guess it makes sense from a memory release POV, but... I end up thinking that for databases using GC or RC is a better approach. Maybe I'm biased, but I have found far easier to work on databases written in C or C#. For that kind of programs I felt Rust overrestrictive and forcing to more dangerous patterns such as replacing pointers with offsets.
