Most likely largely because of this: >Rust downloaded a lot of crates, but that's probably because the Rust version of the code has more features than mine has. For example, it fetched rpassword, a tool that hides password characters as you type them into a terminal, much like Python's getpass function. That's one of the many things I don't have in my code.
