vm

Toy vm from scratch to test some stuff. Used as references the following blogs:

• https://blog.subnetzero.io/post/building-language-vm-part-00/
• https://rust-hosted-langs.github.io/book/chapter-interp-vm-design.html
• https://interpreterbook.com/
• https://nnethercote.github.io/perf-book/title-page.html

Its usage is pretty straightforward, just run cargo run and start feeding instructions via the CLI. The commands available are the following ones:

• .program to show the current program as a Vec<u8>
• .registers the same for registers
• .quit to exit the program
• A B C D, where each value is a valid u8. The tuple can be repeated sequentially and each four numbers represent an instruction.
