Parsing Arguments and Writing Logic in Rust
We are up to Day 37, and today, we are continuing to build out our Rust CLI app. Last time, we set up a simple command-line tool using the clap crate. Now, it is time to dig a little deeper into parsing arguments, handling input validation, and structuring our logic cleanly.
If you are coming from the C# world, this is where you would probably set up your Program.cs to parse args[], maybe use a library like CommandLineParser, and then branch out into your application logic. Rust gives you similar tools but with its own flavor.
