You can use 'unsafe' blocks to delineate places on the hot path where you need to take the limiters off, then trust that the rest of the code will be safe. In C

You can use 'unsafe' blocks to delineate places on the hot path where you need to take the limiters off, then trust that the rest of the code will be safe. In C, all your code is unsafe. We will see more and more Rust libraries trounce their C counterparts in speed, because Rust is more fun to work in because of the above. Rust has democratized high-speed and concurrent systems programming. Projects in it will attract a larger, more diverse developer base -- developers who would be loath to touch a C code base for (very justified) fear of breaking something.
