Thanks. I found and tried that, but what I really needed was a useful compiler error, which Rust did not provide.
Rust desperately needed a usability makeover, last time I tried it.
It amuses me that my fellow security gurus push Rust hard, because we sit in the same policy-pushers conferences as the usability specialists, but we don’t always learn enough from them.
Edit: The responses here are quite revealing. I’m not seeing any of my usability mentors in the Rust diehard fan mix.
None of this has convinced me to give Rust another go. Its community, did not present well here.
