As a huge fan of Rust, I am very interested in people writing comments about what C++ does for them that I'm missing in Rust.
I want more C++ shilling in Rust threads, and I don't think I'm alone.
Please, give me detailed examples of how you can use SFINAE or whatever to express useful misuse-resistant abstractions that can't be expressed with Rust's feature set. Please tell me about classes of bugs you can prevent in C++ that can't be similarly prevented in Rust.
Or maybe C++ isn't safer, but it's more performant? Easier to use? Easier to learn? Easier to troubleshoot and debug?
I agree that the Zig comment that started this sub-thread didn't contribute to the conversation. If we disagree, although I'm not sure we do, it's in that I'd rather call for higher-effort comments about the benefits of other languages instead of fewer comments about them.
- GPGPU programing ecosystem like CUDA and SYSCL (note eco-system, not just a compiler that generates PTX code)
- Game engines like Unreal and Unity
- GUI frameworks like wxWidgets, Qt, MFC, WinUI
- Being the language of choice to contribute anything to GCC or LLVM
- Being the language of choice for the native libraries ecosystem and runtime extensions to plug into Java, .NET, nodejs.
- Being the language to write drivers in macOS (IO Kit/Driver Kit), and Android alongside Java (Project Treble)
- Being avaialble out of the box on macOS, iOS, Windows, Android, Playstation, XBox, Switch SDKs and respective IDE tooling
So you can decide to deal with some of C++ flaws, and enjoy 40 years of history, or spend part of your application development budget into building a Rust ecosytem.
Eigen, although often criticized for its long build times, is still the only linear algebra library that can lazy-evaluate and optimize expressions in compile-time, thanks to C++’s template metaprogramming.
In overall Rust’s current type system isn’t good enough to match what C++ has for numeric computations, although there have been some recent improvements such as the min-const-generics feature. I’ll probably try the language again once const generics are finished.
