Assuming GP's post was not edited, I don't see where it implies that Rust can be used as a C replacement where C++ can't.

It's exciting to see C++ pick up some of those ideas! Anything that improves the current situation is appreciated.

As a counterexample: Stylo alone is already a huge success story, not some "pie in the sky promise that may or may not pan out".

I see what you mean, but I think there are two orthogonal issues here. One is the ownership/lifetime of the heap allocation. That is indeed coupled to a stack object, because non-stack bound lifetimes can (with the current state-of-the

Yeah, if you need "C" style struct representation (which guarantees order), you can enable that on a per-struct basis.

Sure it does. The borrow checker is concerned about lifetimes, regardless of whether the object lives on the stack or the heap.

I think you missed the point of Rust. It's not about replacing new/delete with RAII (even though that's a good idea for sure). How does modern C++ help you with tracking whether a pointer/reference outlives the lifetime

The idea that Rust has the potential to produce faster binaries than C/C++ comes, I guess, mainly from the fact that (once the bugs in LLVM have been fixed) Rust will be able to apply restrict/noalias very liberally to the generat

In Rust (end even C++ afaik) it usually makes more sense to let the callee decide. Does it need to own the value? -> Call by value. Does it only need to inspect or (visibly) mutate the value during the function call? -> Call by refere

You probably think about Leap Motion.

You could bind the web service to the loopback interface of the server. This way it cannot be accessed directly from the internet. Then you can use SSH port forwarding to access it from the web browser on your local machine.

Learning weird new stuff can have a positive impact even though you don't end up using it as your workhorse though. After coding in Rust for several weeks I went back to C++ for my day-to-day work since I'm still more productive w

Yes! Theoretically anything that Rust has support for ( https://forge.rust-lang.org/platform-support.html ) but I think most work has been put into ARM Cortex-M support recently. Especially Jorge Aparicio has worked to make e
