There are lots of guides, tutorials and documentation.

is one I found using a tool called search engine...

Strange. That’s not what I get when I search for “Rust for C++ programmers”. I get flooded with anecdotal accounts/posts from people on Reddit and YouTube talking about their love or hate towards Rust.

Then there’s 3 hour-or-longer videos about Rust which target C++ devs directly. Two are from 2022 and 2019 with one from 2023. Only the 2022 video starts from basics with features that a C++ dev would actually need to understand, like ownership, borrowing, and references. One jumps right into multithreading ideas by discussing mutex. The other jumps into how everything is made “easier” because the compile does borrow-checking instead of having the developer manage it.

These videos probably aren’t bad, but they don’t touch on the larger “gotchas” that C++ maintainers will be scratching their head at, like explicit lifetimes, inevitable headaches with error handling, and reference/target mutability. Some of them are a good start, but they mostly focus on just technical features. It’s difficult to find a resource that helps you learn how to plan out your project early on so you’re not refactoring later due to the topics mentioned earlier.

And to be honest, if you are unable to use them to learn rust, maybe your c++ skills isn't that impressive either.

And this is why 6% of non-Rust users have cited the community as a barrier of entry. Immediate pettiness and hostility rather than trying to get the best resources into the hands of newcomers.
