Intro programming classes will nag you to do all sorts of programming chores: make sure your code actually compiles, write unit tests, write comments, split the code into functions (though sometimes the commenting and factoring advice is bad).

Indeed, such situations exist. I am not advocating for panic-free code. I am advocating that expect should be used for those functions, and if a function is particularly prone to being called like that (e.g. Mut

He’s famous for his YouTube channel as well; I’ve heard good things about it (watching video instruction isn’t really my thing personally). I have also greatly enjoyed his Twitte

As a long-time C++ programmer, and C++ instructor, I am convinced that Rust is better than C++ in all of C++’s application space, that for any new programming project where C++ would make sense as the programming language, Rust would make more
