I don't know. Rust's most successful UI story appears to be "punt and delegate to JS via Electron, RPC, etc." There might be some client-side wasm Model written in Rust that the JS is calling into, but the making of widgets and whatnot is in JS. Note that this parallels all the hipster languages of yesteryear, which invariably answered questions about the GUI story with one of "punt and delegate to C via a thin wrapper over WxWidgets or what have you" or "punt and delegate to the browser via some combination of JavaScript and HTTP." The path for Rust to overtake JS in browser land is something like "compile an already-existing Qt-in-Rust to wasm with some browser-API-specific back end." But Qt-in-Rust doesn't even exist.
