I don't care that it's hard to learn. What turns me off rust is that if I ever make a change that requires a lifetime annotation, I now have to go back through all my code potentially adding lifetime annotations to everything it touches.

I was making a little toy compiler in rust and basically gave up when I wanted to make a change that would have amount to string -> string_view in c++ because in rust I now need to tell the compiler that the String to my &String is going to outlive the struct. Now I understand why it's good but Id rather just let c++ blow my feet off. Maybe once I nail down all the data structures I'll rewrite it in rust.
