rust-by-example VS rust-quiz

Rust can feel a bit intimidating at first but once you start getting the hang of it, you will enjoy it a lot. It has a very well articulated documentation, which can be used as a good learning resource too. Some other resources for Rust include Rustlings and Rust-By-Example.

Rust by Example

Rust by Example: Collection of runnable examples, which many find useful to read

I think something went wrong there, I can find this (merged) PR with https://github.com/rust-lang/rust-by-example/pull/1679/files that has the first example collecting into a string, (which is obv less effective). It was merged 2 weeks ago. I dont know why it isnt online yet.

I more or less went straight from The Book (see also Rust by Example) to Learning Rust With Entirely Too Many Linked Lists and code::dive conference 2014 - Scott Meyers: Cpu Caches and Why You Care and I've often seen PNGme suggested as the next step after that.

Context around the "rust by example" discussion from 2015: https://github.com/rust-lang/rust-by-example/issues/390

The Rust By Example website is another helpful resource for learning Rust. It provides a series of interactive examples that demonstrate how to use various Rust features and libraries.

The book is great and was my original introduction to the language, but rustlings or Rust By Example might be more interesting for an interactive (and more self paced) approach.

Rust by Example: Rust by Example is a collection of runnable examples that cover a wide range of Rust concepts and standard libraries. It's a great way to see how Rust code works in practice.

If you didn't like these because they're "trick" questions you likely also would not enjoy CppQuiz (https://cppquiz.org/)

However you might well enjoy https://dtolnay.github.io/rust-quiz/

Like the C++ quiz, "Undefined Behaviour" is a valid answer, however, the quiz questions are about safe Rust, so that answer is always wrong.

I still get more than half of them wrong unless given far too long to think about it.

Cool, but I feel like the current questions are super basic. Something you're able to answer after reading the book and toying with Rust on a weekend. Definitely needs some harder questions, maybe feel inspired by https://dtolnay.github.io/rust-quiz/?

> If we accept that Rust is indeed more difficult to learn than comparable systems programming languages

My problem is with "comparable systems programming languages". To me the only thing that fits there today is C++ and while a great many programming languages would be easier to learn than Rust, C++ is not one of them by a long shot.

I think the C++ Quiz https://cppquiz.org/ and the Rust Quiz https://dtolnay.github.io/rust-quiz/ illustrate handily. Neither of these languages is a walk in the park, but, notice they both have "Undefined behaviour" as a possible answer? Safe Rust doesn't actually have undefined behaviour, so you get to rule out one of the possibilities any time you don't see the "unsafe" keyword, which is in fact every time on the Rust Quiz. In C++ some of the quiz questions invoke UB, but good luck correctly guessing which ones.

Do you actually want to question all you know about Rust? Do this amazing quiz by the famed dtolnay.

If you want a correct and much harder Rust quiz, here you go.

⭐ Rust Quiz - David Tolnay

One surprise perhaps is that both Python and C++ have multiple inheritance whereas Rust doesn't have implementation inheritance at all (Rust's traits can inherit but data structures and implementations cannot).

Both C++ and Rust have similar Quiz sites:
