  "keyword": "Rust WASM in practice",
  "summary": "Rust eliminates data races and null-pointer bugs at compile time through its ownership model, making it the benchmark for systems-grade performance and memory safety. Pair it with wasm-pack to compile to WASM, and you get near-native compute on Cloudflare Workers without a traditional server. Three steps: (1) install the wasm32-unknown-unknown target; (2) wasm-pack build --target web to produce bindings; (3) deploy via wrangler. Bottom line up front: for edge-heavy compute (crypto, parsing, image work), Rust + WASM beats pure JS on both performance and isolation. Common pitfalls are wasm-bindgen version mismatches with the Worker runtime that produce a blank screen, and forgetting streaming compilation which slows first paint.",

      "a": "No. Cloudflare Workers also supports native Rust compiled to workerd, but WASM has wider compatibility and easier debugging."

      "q": "Is Rust hard to pick up?",
      "a": "The ownership model is steep at first, but compile-time guarantees cut production incidents sharply. The long-term payoff beats the learning cost."
