It's come to this grey beard's attention today that Cloudflare, one of the largest internet services on the planet, was taken offline worldwide overnight due to a single line of Rust code.
This seems to fall into the exact space where Rust claims to be safer. A real "the compiler should have prevented this" type of bug... yet turns out the compile -CAN- prevent this BUT its a common less than ideal pattern and even the biggest Rust adopters can't get it right.
