As a C++ developer Rust’s borrow checker is very interesting - it promises to solve my issues with C++ without the issues that make other languages (ie Java, Python…) have in the real world. (remember we choose C++ for a reason, Java isn’t correct for our application - if Java is correct you should use that instead)
Maybe. I have millions of lines of c++ and making rust work with them will often be more work than just implementing the feature in c++
