Cloudflare published the first public experimental preview of first-class support for the Emscripten wasm32-unknown-emscripten target in the wasm-bindgen toolchain, letting native Rust and Tokio-based applications run on Workers. The effort was started by Google over a year ago and later reviewed and supported by the Cloudflare engineers who maintain wasm-bindgen. To demonstrate it, the team got the Rust-native Minecraft server Pumpkin running inside a Durable Object with TCP ingress using real TCP sockets via Tokio; experimental patchsets and example repos are available now (Building Emscripten Rust Workers, running the Tokio async runtime in a Worker, TCP sockets with Emscripten and Tokio).

Why: Emscripten support uses Node.js compatibility flags to virtualize timers, filesystem operations, and sockets on Workers, which is the missing piece if you previously ruled out Workers for a Rust crate that needs std::net, file I/O, or a Tokio runtime. It is pre-release, so treat the patchsets as a prototype path for a Tokio service or a TCP-ingress Durable Object, not a production migration; if you have a Rust service you wanted at the edge but kept on containers because of missing native platform features, this is the moment to spike a port. No Malaysia-specific detail appears in the post, so local relevance is limited to teams already weighing Workers versus container hosting.
