Rust has semantics which are designed to allow those best practices to be watertight and enforced by the compiler. C++ has semantics which are designed to fit around many years of backwards compatibility with unsafe practices. Attempts to make static analysis for C++ which mirror rust's borrow checker have thus far failed. There is not an automatically enforcable set of rules for C++ in any version which give you the same safety guarantees at rust (and the non-automatically enforcable set of rules is not followable by humans in practice, since we keep getting memory safety bugs in C++ code).
