alt Hacker NewsYeah I'd written some rust ~ 10 years ago when the language was very different and that led me to believe that it was a 'great within it's niche' sort of thing for a long time, but after spending the last couple of years with it as a daily driver I think it's a pretty great general-purpose language.
The one really common gotcha with rust is that when trying to write concurrent code, newbies tend to throw Arc<RwLock<T>> goo around everywhere, and they end up with the world's shittiest garbage collector.

yeah, locks are expensive.

It is interesting to see the different patterns used due to different cases and tastes. For example, my concurrency patterns rarely use locks, and are instead usually one of:
- Dedicated hardware via DMA, multiple cores/MCUs etc
- Thread pools (e.g rayon)
- GPU
- SIMD
- Atomics
- Interrupts and their ISRs
- Event loops
- std::sync Thread and MPSC (My Std rust default for not blocking the GUI etc)➕ show 1 reply
Give me something like boost.multiindex for Rust, and maybe I could think of trying some experiments.
I think C++ is an excellent choice due to its volubility actually. Bc when I want safety, I mostly have it (but I have done a lot of C++, admittedly).
