- jjnoakes 3y agoUnsafe Rust is safer than C++, and even if it wasn't, 5% unsafe in Rust programs (in well-marked locations) is vastly superior to 100% unsafe in C++ programs. Any analogy that equates the two is silly.
- anonymoushn 3y agounsafe rust is less safe than C++ because of the provenance and aliasing semantics that unsafe rust must adhere to to avoid UB, which are generally tricker than those of C++
- tialaramex 3y agoThe provenance rules in the C++ standard are basically just a shrug emoji†, so it's unclear whether those are worse, I can see an argument for the idea that obeying Aria's strict provenance experiment rules in Rust is easier - not because it's easy (although for many common cases it is) but because at least these are coherent rules. † U+1F937 person shrugging
