ultraviolet VS ros2_rust

This one has some more traction: https://github.com/fu5ha/ultraviolet

Some other good places to look would be the source code for the ultraviolet crate and for wide.

2. Using macros for codegen, as seen in almost all other linear algebra crates, e.g. ultraviolet (https://crates.io/crates/ultraviolet)

The drawback of (1) is that it's hard to understand or extend, and the type errors are insane, and put Boost to shame. The drawback of (2) is that's just a macro. Of course (1) and (2) are not interoperable.

C++ templates are really underappreciated, because they are a single mechanism that gives you both powerful generics and macro-like codegen, while being easy to adopt gradually. (E.g. you can add concepts when it gets unwieldy, but you don't have to rewrite the whole thing.)

I want to make this happen ! Do you know of any good robotics framework in Rust, as of today ? I heard that ROS2 was slowly including Rust [1], not sure at how did it go. Ros would be a good entry door to sensor fusion, mapping and localization. Because all of the hardware integration / abstraction is already done (in C++). I'm curious to know if company are using this.

The rosrust crate is for ROS1. You either want to switch to that instead or use a crate meant for ROS2 (I think the main crate for that is ros2_rust).

How about: https://github.com/ros2-rust/ros2_rust/blob/main/docs/writing-your-first-rclrs-node.md

We're happy to announce a new release of of ros2-rust!

After many months of hard work we're happy to announce [a new release](https://github.com/ros2-rust/ros2_rust/releases/tag/0.2.0) of ros2-rust. This new release includes lots of improvements and features, some of them are:
