You just make learning Rust look fun :)

Your chat did you dirty. Starting with clap is probably not recommended 😂. You can do this with normal argument parsing. Clap is a more full-fledged solution for production CLI apps

Nice video, great to see someone enjoy rust! But in the "overall impressions" the argumentation of "code wasnt too crazy" point is wrong imo: You're saying that the "low level code" is not as bad as people who use "higher level languages" assume, except what you are talking about has nothing to do with the "low-levelness" of rust (which is questionable: it has got a lot of high level concepts compared to lets say, c, and that just goes to show that the "level" of the language is relative), in fact the stuff you use as an example (pattern matching) is a rather high level construct. Your code doesnt have low level parts, you didnt need to worry about the hardware you're working with `at all`, the memory was managed for you, and the syntax was just unusual to you, but its not related to "low levelness" at all.

Yeah that makes sense. I think I was using "low level" to refer to the fact that the resulting compiled code runs directly on the hardware as apposed to being interpreted, just in time compiled or running on top of a runtime like .NET or the JVM.
