Cloudflare says developers can now build and deploy Rust libraries and applications that its Workers platform previously did not support. Experimental support for the Emscripten target enables those programs to run on Cloudflare's global Workers platform.

The change expands what Rust developers can deploy there, but the support remains experimental. Cloudflare says support for Tokio, a library used to run asynchronous Rust programs, is still forthcoming.
