I too am impressed by Cloudflare Workers’ potential.

However Workers supports WASM so you don’t necessarily have to switch to JavaScript to use it.

I wrote some Rust code that I run in Cloudflare Functions, which is a layer on top of Cloudflare Workers which also supports WASM. I wrote up the gory details if you’re interested:

JavaScript is most definitely the path of least resistance but it’s not the only way.
