How to bridge Rust and Swift for a GPU tile engine: Cargo workspace setup, C-ABI FFI with cbindgen, static library linking in SwiftPM, and practical patterns from Astropad's liquid-next codebase.
Deep dive into Astropad's tile-based LIQUID protocol: GPU-accelerated tile diffing with Metal compute shaders, adaptive codec switching between tiles and H.264/HEVC, LZ4 compression, and the architecture that achieves 16ms end-to-end latency.
Context Run Qwen3.5 27B locally at Q80 quantization, split across 2x RTX 3090. NVIDIA driver modules are mismatched with the running kernel — must fix first....
