And you want to embed that server by compiling to wasm? I would assume so, and it being in WASM means they can use the exact same binary code on the server and in the webbrowser. You could of course do the same thing by writing in Javascript (running in Node on the server or in the browser) but then you are in JS instead of Rust.
