[Other] Show HN: Inception: Automatic Rust Trait Implementation by Induction Hi HN,<p>I thought this would be a good place to share a little puzzle I&#x27;ve been working on. Inception is a Rust library that helps you share behaviors in Rust using structural induction. Practically, this means that instead of having a derive macro for each behavior, a single derive can be used to enable any number of behaviors. It doesn&#x27;t do this using runtime reflection, but rather type-level programming - so there is monomorphization across the substructures, and (at least in theory) no greater overhead than with macro expansion.<p>While there are a lot of things missing still and the current implementation is very suboptimal, I&#x27;d say it proves the general concept for common structures. Examples of Clone&#x2F;Eq&#x2F;Hash&#x2F;etc replicas implemented in this way are provided.<p>The code is not idiomatic, which is my biggest reservation about continuing this work. It was fun to prove, but is not so fun to _improve_, as it feels a bit like swimming upstream. In any case I hope some of you find it interesting!

[Other] Show HN: Open-sourcing our text-to-CAD app Hey HN! I&#x27;m Zach from Adam (<a href="https:&#x2F;&#x2F;adam.new&#x2F;">https:&#x2F;&#x2F;adam.new&#x2F;</a>). We’re building an AI co-pilot for mechanical CAD software.<p>As part of our broader research, we built a browser-based Text-to-CAD app (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206</a>) and are now open sourcing it. This is a React SPA with a Supabase backend.<p>What it does:<p>* Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references<p>* Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension tweaking<p>* Exports as .STL or .SCAD<p>Under the hood:<p>* Separate agents for conversation and code generation; simple parameter tweaks bypass AI entirely using deterministic regex-based updates<p>* Runs fully in-browser by compiling OpenSCAD to WebAssembly and integrating Three.js with React Three Fiber for 3D rendering<p>* Supports BOSL, BOSL2, MCAD libraries and custom font support (Geist) for text in models<p>We’ve seen many developers trying to replicate this kind of functionality, so we’re releasing this to give the community a solid foundation to build on.<p>Future improvements:<p>* Expand geometry support - Move beyond CSG primitives to support curved surfaces, fillets, lofts, and constraint-driven modeling through CadQuery&#x2F;Build123D<p>* Better spatial context - UI for face&#x2F;edge selection and viewport image integration to give LLMs spatial understanding<p>* Enhanced capabilities - RAG on documentation and integration with more OpenSCAD libraries for features like proper threading<p>You can clone the repo and run it locally! Contributions are welcome, and we’ll keep merging PRs as they come in.
