I came across post in which talking about C++, to have safety features as in Rust. You can find post here: link.(in post saying about, what committee want to add, with proposals beginning from introducing safety profiles to implementing a borrow checker similar to Rust)
Currently, C++ making security standart is depends not only developers itself of C++, but mostly programmers, who uses safety features in C++ language, such as smart pointers: std::unique_ptr, std::shared_ptr, std::weak_ptr.
C++26 is still under development as well as C++29. Approximately C++26 will be out in 2026 year.
