I agree, but what I'm saying is, it only generates the numbers once and then sorts them 500 times. Yes it's a flawed measurement because it measures the generation time + 500 sorts, but the time to generate the numbers is probably

Made a PR with the fixes, Rust is now 3 times faster than tinygo, and the wasm is almost 3 times smaller (wasm+js is twice as small) as expected. https://github.com/Ecostack/wasm-rust-go-asc/pull/1 My first f

It's also not measuring rng speed, it's measuring memcpy and sort speed.

Your go uses `pdqsort` to sort 4 byte ints from 0 to 100, while rust uses a stable sort (`sort_unstable` is equivalent to `pdqsort`) on single byte integers from 0 to 255. Hardly a fair comparison.

You typically use build-std and possibly abort on panics or immediate-abort to disable the string formatting code in stdlib, and you do fat LTO. after stripping the binary, it’s pretty damn small. If you want even further savings on std, yo

How is it different from "If you ever go down the JNI road in Java"? Be it a library the bundles RocksDB, or Android stuff, doesn't matter that your average Spring Boot developer probably won't be having any native depen

I don't even disagree with these points! But if you go down to language lawyering and semantics, I think one could technically make a case for Rust being safer (in the memory safety sense) than Java/Go/(insert any GC'd m

No one is writing kernels, raw register level volatile DMA bit-banging embedded code, and other "impossible without unsafe" code in Java/Go (Ok, almost no one, don't @ me, pjmlp, there are kernels built in memory-safe la

Both Java and Go also have unsafe, and are often used for FFI/Performance, and some popular/foundational libraries (like Google's Protobuf library in Java) use unsafe just for added performance. Heck, Go has an Assembler. So

> For regular application code there's no real benefit Can't disagree, naive garbage collected code would outperform naive Rust code that allocates Strings and Vecs up the wazoo. And performance isn't a real issue with sim

Do you want to use AVX-512? Zen 4 is your only real option out of the three. They disabled AVX-512 on Golden Cove due to Gracemont not having it, and not having implemented any sort of AVX-512 workload CPU pinning like idk, SIGILL trapping?

I think you meant Espressif, Steve. They have a fork of LLVM with Xtensa support they’re looking to upstream (still a few things missing, like the DSP/AI instructions in ESP32-S3, and I think the codegen is better on GCC for now). And

If we're talking about wish-lists, encoding performance on low-power IoT devices, maybe? It has decent SIMD support on ARM/x86 and tweakable complexity settings, but if your device is weaker than an ESP32, you'll be hard-pres

I use Zig and cargo-zigbuild to cross-compile my Rust projects. It simply works, without Docker, if I want it to use older GLIBC symbols for an embedded Linux target running an ancient kernel/glibc version, or if I want to cross-compil

Well, for one, in the Rust version, check(i32::MIN) will return false if built with overflow checks disabled (the default for release builds). C++ will of course always return true.
