What Next?
Excellent work. Rust takes practice, so keep writing small programs. Next, read about traits, generics, lifetimes and error handling with ?, then try building a command-line tool with Cargo.
The Rust compiler is your teacher. When it shows an error, read the whole message: it often tells you exactly how to fix the problem.
