Happy to see more rust!
I’m geniously curious : Is there a difference in binary sizes? 5%? 10%?

Looks like it's split in library and binary, the binary itself is smaller, but if you add the size of the library it would be about 10% bigger. At least judging by the package sizes.

Great, massive step forward. Rust’s memory safety will prevent potential PE vulnerabilities (and more).
