 ## Unsafe stuff
-- incomplete featured enabled with a flag `#![feature(type_changing_struct_update)]` ([https://rust-lang.github.io/rfcs/2528-type-changing-struct-update-syntax.html](RFC2528)) enabled me to use  syntax for destructuring structs between each other in typestate context (ok to use in this toy project)

 ## Missed out on some things 
 - 100% test-coverage
 - deep analysis and correct implementation of all business use cases and edge cases
-- code comments, and CI/CD'ing `cargo doc` output into GitHub Pages with GitHub Actions
 - beautiful error logs
