Rust for C++ developers - What you need to know to get rolling with crates - Pavel Yosifovich

Built-in memory safety. Ownership model and borrow checker ensures that your values aren't being thrown around all over the place. Example: https://pastebin.com/w1dtmxbc This program won't compile becuase you are using an immutable variable while there's a mutable variable in the same scope. This is something the C++ compiler doesn't check for, but this feature ensures safety. What if you modify 'y' and then read from 'z' expecting the previous value? Something else that is also amazing in Rust is the multithreading. It is much easier to keep an eye on who's accessing what, instead of using the 'mutex' keyword in C++.

I think that if you show problems like Use after free, Dangling pointer, and other common memory problems that Rust try to sove using the borrowing and ownership concepts is a good start to introduce the language. There are a couple of videos where you can find some code examples comparison and languages features differences.
