How can I convert a impl Future<Output = JsValue>
to a js_sys::Promise
?
The XY problem is as follows:
pub async fn handle(self: &Rc<Self>, s: &str, v: &JsValue) -> JsValue { todo!() }
We want to create a function of type signature:
pub fn handle_sync(self: &Rc<Self>, s: &str, v: &JsValue) -> js_sys::Promise {
let x = self.handle(s, v);
??? how do we convert x to a js_sys::Promise ???
}
This only needs to work on target=wasm32-unknown-unknown
Basically I have an async Rust function. I want to wrap it in such a way so we can pass it as a callback to JS function.
