In my experience, Copilot is not able to fix rust code flagged by the borrow checker. Its suggestions are almost always wrong.This is a hard problem and often requires restructing the code (and sometimes using inner mutuability constructs such as RefCell and so on).
Interesting and timely article! On an Ubuntu guest (Windows host), I install the Samba server and then use the native Windows CIFS client to connect to the Ubuntu host. This gives me the advantage of vm (virtualbox) native filesystem and letting me use my windows machine to open files on the guest
Perhaps this support can be added to some later version of vagrant
