I'm fairly proficient in Rust and I think it has its own strengths for learning, but its own downsides too. Pros: 1. Way easier to get "live" help, I've found the barrier to ask for Rust help is lower than any other language I've ever used (and I've used a lot) 2. Way easier tooling like cargo, error messages are far better, especially with regards to generics vs templates 3. Some things are more explicit in Rust. Like `Box<dyn Trait>` is very explicit about dynamic dispatch, I don't recall that being the case in C++. Cons: 1. Rust's "codex" of knowledge is nowhere near C++. There are tons of conference talks, books, blog posts, etc on C++. Not just on C++ but also on hardware as seen through C++, security, etc. 2. Implementing low level data structures in Rust is an advanced practice. Implementing them in C++ is trivial. I get that it's trivial because C++ doesn't give a fuck about your pointers, but if you're just trying to learn data structures you really just need to be focusing on happy paths and whatnot (as a student). So idk, at this point I tend to recommend Rust, but I also end up having to link people to talks on C++ sometimes! Herb Sutter and Scott Meyer are amazing speakers and writers and that's a very hard thing to replace.

An accurate summary. I was reflecting exactly your cons when I left gaps in what I said Rust was good for. Con (1) (Existing examples / training) is a legacy language strength in general, C++ is going to lead in this for a long time. Con (2) (Low level data structures) I 100% agree. A toy example of a datastructure in C++ is going to be really easy to express but also dangerous to use. I think you'd really enjoy this chapter of the Rust Docs on making your own Vec https://doc.rust-lang.org/nomicon/vec/vec.html https://doc.rust-lang.org/nomicon/vec/vec.html And you are correct (Con 2 again), it IS an advanced practice. The result of making a data-stucture the rust way is a bulletproof class anyone can use, rather than a C++ foot-gun so it's worth the effort (but less so for learning). You might find you can make your whole module unsafe and write a very similar data-structure in rust to your C++ solution (pointers and all) and it would compile and run fine.

  The big thing to know about rust datastructures is that you need to use unsafe to implement anything cyclic. There is nothing wrong with using unsafe for a few lines of code - just review carefully.
