Code review wanted, looking for improvements

In addition to what's been said, already, you may also want to consider using my_result?.do_something() and returning the Err to the caller and let them handle it. You can even return a Result from main. I highly recommend you to read the error tutorial posted on this forum.

Rust Error Tutorial

There's a lot of do_something.unwrap() floating around the Internet of Rust tutorials, so I got inspired to write a tutorial on error handling in Rust to supplement the really excellent chapter in the Rust book. I hope this helps someone and welcome any feedback/suggestions for improvements!
