Its signature feature is memory safety without a garbage collector: the compiler enforces rules that stop the crashes and security holes that plague older systems languages. That makes it attractive for software where a single memory bug could be catastrophic.
The cost is a steep learning curve. Rust's strictness that prevents bugs also makes it harder to learn and slower to write at first. It's overkill for a typical website, but excellent when speed and reliability are non-negotiable.
