Programming

Maybe the problem is, that you try to learn and use everything at once. Rust is not easy and it has lot of stuff to learn and get good at. And compared to many languages, Rust has a few set of core features that makes it more complicated to understand and also you need to learn the basics before getting started. So just doing the exercises is not enough. My advice is to write simple programs with a focus of specific set of language features and what you want to accomplish, before doing the more advanced stuff.

The difference to languages like C++ is, that Rust forces you to do the homework before running the program, not after. That is the reason why it looks to be "harder", but I think this is one of the reasons why its so misunderstood. In example if you MUST think about all possible states, variables and errors in a program before it runs, then you have to put so much work for this. In the end, you did all the work and the program should theoretically better than if you did not have. Compare this to other languages, where you can run the program simply by ignoring errors, all states a program can be in and be done in short amount of time. That looks easy. But in reality you didn't do all the work.
