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.

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?
