> I’m not convinced by leptos’s html style view macro. It’s cute, but you lose out on autocomplete and other IDE integration. Yes, that was exactly my thinking. In addition to more natural IDE support, relying on plain-old-Rust and not having a macro-processed DSL for the view specification makes it more comprehensible for LLM-driven development and testing (since the agents will likely know how to write correct Rust, but struggle with a bespoke DSL that it hasn't been trained on). > Leptos signals are Send. You can write to them from other threads. That's nice — I wasn't aware of that. Day's is main-thread-only, which is currently a significant limitation. I'll definitely look closer at leptos’s reactive_graph for ideas. > You're also using SwiftUI's layout, while I'm leaning on taffy instead for css-style flexbox / grid layout support. I'd love to know more about the deep tradeoffs going on here. I was tempted by Taffy, since it is very mature and widely-used, but ultimately chose to have the clankers implement something homespun for Day. One of the major reasons was that I can have fine-grained control over the measure passes for optimization. Measuring is cheap for most platforms, but Android (for example) requires a FFI hop via JNI to communicate back and forth between Rust and Android's Java SDK, and that can be quite expensive. So being able to control how these requests are batched together and optimized was important for getting good performance there (and also potentially for ArkUI and other platforms that don't have C/C++/ObjC bridges directly into their UI frameworks). More broadly, though, I feel like Day's SwiftUI-style "parent proposes size, child decides" paradigm is better suited for native components, which tend to have more non-negotiable requirements for many of their control sizes and layout. > Write and post about it - this is cool! Yes, I plan to!
