Craig's Amazing Rust Spectacular
summary
TypeScript lattice Boltzmann fluid sim is ported to Rust, built with cargo and measured: JS sim runs ~32 ms/frame, Rust native runs ~13 ms/frame, so about 3x faster. Renderer prototype targets terminal for raw speed, then Rust compiles to WebAssembly using wasm-pack and exposes memory; the browser reads the Rust heap via a Uint8Array memory buffer and paints a canvas, achieving sub‑16 ms frames and real‑time 60 fps.
