I've only ever used GCed (and largely dynamic) languages up until now (Python, JS and Clojure primarily); C is alien and C++ is frankly terrifying.

I would looooove any insight that you have on making the docs better for people who haven't done systems programming before. If you've ever got the time to type out a few thoughts, my email is in my profile.

Maybe you could make a survey that people who read these tutorials/guides/introductions could take after reading them?

Out of curiosity I implemented the two examples in C++11. For the number add I used a unique_ptr (although returning by value would be better in every way). For the shared state I used async with a lamba that calls transform and returns the modified vector through a future. This doesn't execute in parallel for each for loop though. I think something like Arc can be coded in C++ too - template wrapper that returns a R…

C++ is not safe, and we still see tons of memory safety issues, many security-sensitive, in practice, despite using modern C++ for all new code. Even if safety isn't as important to you, there are other reasons you might be intereste…

What are concepts in this context? It is hard to google.

The docs are great, and the fact that numerous examples with line-by-line explanations are coupled with higher-level prescriptions makes the docs great. Often documentation is too formal, and this formality makes it difficult to follow.

On the other hand, the writing style is way too "cute". It is legitimately distracting to see all these "Hooray!" and "Wait, whaaaat?" and "Not too shabby! I love eliminating mutable state.". It's unhelpful at absolute best.

Otherwise - thank you very much for this. Your docs are undeniably crucial for the adoption of Rust and they're extremely helpful.

Thanks. Yeah, I specifically have a thing open for it being too much in my own voice. Since this was basically ported wholesale off of my blog, it was better there...

And you'll be happy to hear my contract includes examples for _everything_ in the stdlib, so get ready for more of those!

Maybe. I'll give it some thought.

Is this something that can be used in Rust? Or is it a feature that will be implemented later?

I am not familiar enough with the details. We don't have an _exact_ analogue, though our Traits are similar-ish.

I've pinged #rust, I'll see if I can get someone who knows more to answer here.

Amazing to hear that. It's an exciting time. Thanks again!
