Is there any way to call async function inside scope block?

[jjeffcaii]

struct MyService(String);

impl UserData for MyService {
    fn add_methods<'lua, M: UserDataMethods<'lua, Self>>(methods: &mut M) {
        // bind a async function here...
        methods.add_async_method("my_async_call", |lua, this, _| async move {
                 // ...
        });
    }
}

let script = r#"
function handle(svc)
  svc:my_async_call()
end
"#;

let lua= Lua::new();
lua.load(script).exec()?;

async fn foobar() {
  let svc = lua.create_userdata(MyService(...))?;
  
  let globals = lua.globals();
  
  let handler = globals.get::<_, Function>("handle");
  
  vm.scope(|scope| {
      // QUESTION: Is there any way to call async in the scope???
      handler.call_async(svc).await?
  })?;

}

Only if you use block_on function to execute future.

Generally to provide (safe and sound) async in scope mlua needs to define an executor interface and bind to tokio (for example) which is not something I'm planning yet.
