Except that many other languages have proven that C++ is simply terrible at providing meaningful errors.
The whole point of a segfault is that you can’t really know anything about it. Even in rust, when you get a segfault there is no meaningful error.
point is, Rust manages to give you not a segfault but a meaningful error almost all the time until you use unsafe
If you’re getting a segfault in C++, it’s also cause you used unsafe code. It’s just not officially enclosed in an “unsafe” block.
the point was not on the unsafe word, but a very specific feature of Rust that helps enclosing unsafe code where the compiler wouldn't be able to 100% verify your logic. no such thing in C++. C++ does not even attempt to verify safety
your response is basically "get better at coding dumbass, I am the safety validator"
