Could you provide some examples of C++ features that the Rust team has consciously chosen to not support, to try to keep the language more approachable? Could you show some examples of how you need to work around these deliberate limitation

I've never actually used TSan, so please correct me if I've missed something significant about how it works, but doesn't TSan need to observe the race happening in order to detect it? The code coverage analysis I've seen

This description doesn't match my experience of writing Rust at all. During the exploratory phase of my projects, I very rarely run into nontrivial lifetime issues, and when I do, I can just put whatever data into an Arc and then it ju

One other underappreciated point is how to deal with other resources besides memory. Go has a GC, which helps with memory, but you're entirely on your own for files, sockets, database connections, mutexes, channels, etc. The features t

This really matches my experience, in that learning the Go language is very simple, but learning to correctly use the Go language to reliably build correct programs is much more difficult. The Go compiler (and other tooling like go vet and

Like you said, this is a variant type that represents either a value, or an error. Here's the definition of Rust's Result type: pub enum Result<T, E> { Ok(T), Err(E), } I threw together some examples of

Yes, I agree, you can implement a doubly-linked list in Rust exactly as you can in C, with the same precise control. You can even implement intrusive collections: https://docs.rs/intrusive-collections/ Unsafe is a norm

The point is that the sane, correct choice is also the easy, default choice in Rust. We've been able to implement (ptr,len) buffer types in C for as long as we've had C, but uint8_t* is both baked into many APIs, and the path of
