Show HN: Integrate – a Rust crate for numerical integration (+ an mdBook guide)

I recently built Integrate, a Rust crate designed to make modular integration in Rust projects smoother and more ergonomic. If you've ever struggled with structuring Rust applications or composing independent modules cleanly, this crate might be useful for you.

To make adoption easier, I’ve written a comprehensive mdBook that explains how Integrate works, real-world use cases, and best practices: https://mtantaoui.github.io/Integrate/

I’d love to get feedback from the Rust community! Does this approach make sense? Are there features or pain points you think should be covered?

Looking forward to hearing your thoughts!
