No, you are wrong. Rust compiler bug uncovered this month was aboıt memory safety: https://www.penligent.ai/hackinglabs/rust-borrow-checker-bug....

Basically, the borrow checker allowed writing memory unsafe programs without using the keyword unsafe.

Compilers for C, C++ etc. are well established but Rust is a relatively new language. There are many bugs to come just like this.

Using a memory safe language is not a silver bullet for writing memory safe code. The implementation of the memory safe language introduces bugs as well.
