It didn’t. My C library read garbage bytes, segfaulted, and made me question all my life choices. That’s when I discovered Rust’s representation attributes — repr(C), repr(transparent), and the wild, undocumented world of how the compiler decides where and how yo...")

But something subtle and revolutionary is happening beneath the surface: WebAssembly (WASM) is creeping out of browsers and into backend servers. And Rust is the language leading that charge.

You’ve got a bunch of trait objects (Box<dyn Trait>, maybe nested ones), and you think,
“If trait Child extends Parent, surely I can treat a Box<dyn Child> as a Box<dyn Parent>.” Then Rust laughs in your face.
No — you can’t just upcast a trait object. For years, this was one of those things we all hand-waved...")

“value borrowed here after move.” But the borrow checker is not just a compiler feature.
It is a design mentor that shapes the way you think about data, concurrency, and safety.

Until I built a CLI tool with a few generic data structures and the binary ballooned from 2 MB to 37 MB. I thought I had accidentally compiled in debug mode.
Nope — it was Release.

Not a small one. A production outage that took down half the pipeline at 2 AM.
No warnings, no smoke — just silence. One dangling pointer in a C++ service corrupted a message queue.

The fix took one hour.
The recovery took three days.
The trust took months. That week changed how I thought about system design.
It was the week I picked up Rust.

It’s like asking a poet to write machine code — in rhyme. A bootloader sits at the very edge of the known world — the first thing your CPU runs after power-on, before any OS, heap, or even std exists.
