Rust has a bit of a steeper learning curve at the start, but it pays off once you get used to it. C and C++ are deceptively simple at first, but as time goes on you keep discovering more nuances that affect most of your code. There's no real problem starting with Rust, especially if you have some experience with other languages. The biggest difference is going to be getting used to dealing explicitly with memory, since all the languages you listed have a garbage collector; but this is true of all of C, C++ and, Rust. Be kind to yourself -- don't expect it all to click instantly.
