Most hardware-level observations, like the latency of various memory accesses or numeric operations, would be the same for the Rust code. As for higher-level abstractions, I've already started porting them to Rust <https://github.com/ashvardanian/less_slow.rs>.
Next, it would be exciting to implement a concurrent job-stealing graph algorithm in both languages to get a feel for their ergonomics in non-trivial problems. I can imagine it looks very different in Rust and C++, but before I get there, I'm looking for best practices for implementing nested associative containers with shared stateful allocators in Rust.
I’m definitely interested in seeing this kind of content in Rust, have you looked at Rayon’s implementation for work stealing yet? Can result in some very nice high-level code.

In C++, I've implemented them like this: <https://github.com/ashvardanian/less_slow.cpp/blob/8f32d65cc...>, even though I haven't seen many people doing that in public codebases. Any good examples for Rust?
