Based on my personal experience, I think it might also be helpful to have an even shorter version tailored to "Rust for C++ programmers", which I find to be useful because you can mostly just go "ok here's the syntax for basic things, here is how lifetimes work and what problems they solve, here are the replacements for things you are familiar with and why some operations are not available for them". In particular, this lets you skim over "What is the stack? What is the heap?" that many introductions will spend time on.
