Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[Media] I'm comparing writing a double-linked list in C++ vs with Rust. The Rust implementation looks substantially more complex. Is this a bad example? (URL in the caption)
itโs even written by the same person that wrote the Nomicon (the guide to the dark arts of unsafe)

Rust books to read
If you want to dive deeper you can always have other options but now there are concrete cases, if you want to do low level thing https://doc.rust-lang.org/nomicon/ while if you want multi thread/concurrency stuff https://marabos.nl/atomics/ . There are many many books so you will have to point yourself to what you want

Thread-shared boolean flag
Nonononono. SeqCst is the most error prone memory order: https://github.com/rust-lang/nomicon/issues/166

[Media] Hashmap behaviour inside a loop due to lifetime issue
Hope this helps. For more details, see the Rustonomicon. I referenced the subtyping chapter here extensively.

Unsafe Rust
Nice video! Glad I could help out. This stuff is hard, and I'm still learning a lot about it myself even years later. The Rustonomicon is a great read if you haven't already.

Stepping up the YAML engineer game
Have you got a moment to read through the good book , after reading through this perhaps try the Rustonomicon.

CppCon 2022 Best Practices Every C++ Programmer Needs to Follow โ Oz Syed
That is not what UB means. Undefined Behaviour is behaviour that the compiler is allowed to assume will never happen, and which can consequently cause miscompilations due to optimisation passes gone wrong if it does in fact occur in the source code.
It's true that Rust does not have a written specification that clearly delineates what is and isn't UB in a single place. But:
1. UB is impossible in safe code (modulo bugs in unsafe code)
2. There are resources such as the Rustinomicon (https://doc.rust-lang.org/nomicon/) that provide a detailed guide on what is and isn't allowed in unsafe code.
In practice, it's much easier to avoid UB in Rust than it is in C++.

How to write deserializer for custom binary protocol?
However, this is a wide topic out of scope for a Reddit comment, so maybe just read the Rustonomicon. It explains everything about data handling in Rust.

Performance critical ML: How viable is Rust as an alternative to C++
The ownership model & borrow checker makes rust a bit of an awkward language in which to write complex data structures like trees and graphs. It can be done - since you can always use raw pointers & unsafe code when you absolutely need to to treat rust like C. But the language fights you, and the community can get a bit moralistic about this sort of thing. The rust nomicon is a fantastic resource for learning the limits of the borrow checker, and where and how to use unsafe code correctly. You will need unsafe less than you think you will, but sometimes you will have no choice.

Stuck at 4.3 of the rust book. It's so hard for me.
There's also Easy Rust, an effort in translating the Rust Book into Simple English (limited vocabulary, limited use of idioms), which has now become a Book.

Easy Rust has been reborn on Manning as Learn Rust in a Month of Lunches
Up on Manning starting this week is a book I wrote / am writing called Learn Rust in a Month of Lunches, whose origins date back to Easy Rust that people here might be familiar with and which I wrote 2 years ago. The first six chapters are now up on MEAP which is pretty exciting. (The code mlmacleod gives 45% off until February 2 btw)

I have returned
Along with the Book, I wrote a book after learning Rust that's for absolute beginners, and doesn't even require installing Rust. It's almost entirely done in the Playground so you can just open up a tab in your browser and follow along. As far as paid books are concerned, my favourite is Programming Rust.

What is the best course to start learning?
I made a book for absolute complete beginners, after which the Book should be easy to understand. After that I'd recommend Programming Rust (my favourite book on Rust).

Newbie here. Just finished reading the book. What now?

Rust course
Depends on what language you come from. I found this a decent enough intro for most languages: https://github.com/Dhghomon/easy_rust

I have to admit. The free code camp course is a bit more sparing than I would have preferred. How did everyone learn Rust?
This is my favorite: https://github.com/Dhghomon/easy_rust

It's been 20 days since I started learning rust as my first language. Terrible experience. Should I move forward?
I put together a book that goes over most of the same content found in The Book but written with easy / straightforward English (partially for English L2 speakers but also for English speakers that just want the info in as straightforward a package as possible).
What are some alternatives?
book - The Rust Programming Language
too-many-lists - Learn Rust by writing Entirely Too Many linked lists
mdBook - Create book from markdown files. Like Gitbook but implemented in Rust
rust-by-example - Learn Rust with examples (Live code editor included)
rust-ffmpeg - Safe FFmpeg wrapper.
Rustlings - :crab: Small exercises to get you used to reading and writing Rust code!
Theseus - Theseus is a modern OS written from scratch in Rust that explores ๐ข๐ง๐ญ๐ซ๐๐ฅ๐ข๐ง๐ ๐ฎ๐๐ฅ ๐๐๐ฌ๐ข๐ ๐ง: closing the semantic gap between compiler and hardware by maximally leveraging the power of language safety and affine types. Theseus aims to shift OS responsibilities like resource management into the compiler.
Rust-Full-Stack - Rust projects here are easy to use. There are blog posts for them also.
Exercism - website - The codebase for Exercism's website.
miri - An interpreter for Rust's mid-level intermediate representation
