There's nothing like reading data from files in Rust.

Like any other programming language, one way to do it would be too easy, so there are, of course, way more ways than anyone can count.

Gladly, there are a few idiomatic ways we can go over in this video!

How about a short on the pros of learning Rust as a language ? Why would someone want to / should learn rust?

I like that you keep it in clean rust, but maybe you could mention crates to help - if they exist
