Because it's 5 times more complex, you need to get the maximum performance available. Therefore more ASM than ever.
Rust does not bring more performance. Just more safety.
The safety can be worth it in certain cases. Like when handling untrusted input. And it's not just Rust: look at WUFFS for example. WUFFS can actually rival handwritten implementations in certain cases.
