5 Rust patterns that replaced my Python scripts

I used to reach for Python every time I needed a quick script. File renaming, log parsing, API polling, directory cleanup -- Python was the default because it was fast to write and good enough to run. That changed gradually. Not because I decided to rewrite everything in Rust, but because I kept running into the same friction points: shipping the script to another machine, handling errors properly, or running it somewhere Python wasn't available. Here are five patterns where Rust has genuinely replaced Python for me. 1.
