More of my philosophy about memory safety and inheritance in programming languages..
I am a white arab from Morocco, and i think i am smart since i have also invented many scalable algorithms and algorithms..
"Address sanitization is not a security feature, nor does it provide memory-safety: it's a debugging tool. Programmers already have tools to detect that the code they've written has memory problems, such as use-after-free or memory leaks. Valgrind is
probably the best-known example. This gcc feature provides (some of) the same functionality: the only new thing is that it's integrated with the compiler, so it's easier to use.
You wouldn't have this feature turned on in production: it's for debugging only. You compile your tests with this flag, and automatically they detect memory errors that are triggered by the test. If your tests aren't sufficient to trigger the problem,
then you still have the problem, and it'll still cause the same security flaws in production.
Rust's ownership model prevents these defects by making programs that contain such defects invalid: the compiler will not compile them. You don't have to worry about your tests not triggering the problem, because if the code compiles, there cannot be a
The two features are for different sets of problems. One feature of address sanitization is to detect memory leaks (allocating memory and neglecting to free it later). Rust makes it harder to write memory leaks than in C or C++, but it's still possible (
if you have circular references). Rust's ownership model prevents data races in sequential and multi-threaded situations (see below). Address sanitization doesn't aim to detect either of those cases."
And using just plain C#, it has better memory protection, since the GC and runtime make it impossible to leak, double-free, or access out-of-bounds. C# has unsafe blocks just like Rust does. Safe Rust is just as safe from memory safety problems as safe C#
I think that a programming language has to provide "inheritance",
and the new Rust programming language doesn't provide it and i think that it is a deficiency in Rust, here is why:
As a software developer you have to become more efficient and productive. So you need to make sure the code you write is easily reusable and maintainable. And, among other things, this is what inheritance gives you - the ability to reuse without
reinventing the wheel, as well as the ability to easily maintain your base object without having to perform maintenance on all similar objects.
