Coincidentally, I personally started learning Rust as C++ was a lot more difficult to learn by myself. The Rust book[1] is a great resource as it makes learning pretty complex topics fairly easy to approach.

Personally the thing that really sold me over was the "Building a guessing game" section, as it showed how to use the build system to pull in external libraries. I found these aspects specifically difficult to learn when learning C++. Plus, after learning Rust, I was able to go back to C++ and better understand it. Still have no clue about build systems though.
