Parse CLI Arguments With Rust Standard Crate 🦀📦 Rust Tutorial
Ғылым және технология
When you're building Rust applications, you'll oftentimes want to pass in user defined command line arguments. Although 3rd party crates exist for parsing CLI arguments, Rust also has built in functions that help you retrieve argument values. In this video, we'll explore how to retrieve and parse cli args, without importing any third-party crates!

17:10 isn't .next() enough since it gives you the next one item?

You mean calling .skip(1).next() instead of .skip(1).take(1).next()? It's possible, I'd have to try it again 🙂

@@TrevorSullivan yeah, also, I think .take() will create a new Iterator, which can incur some performance hits.

Should I learn rust despite all that's happening out there?

In my opinion, yes. All communities suffer from division and restructuring at some point. Just don't become part of it, and focus on building good software. That's my advice.
