this result above is giving result.is_promise() true. which i expect it to. But i do not understand why it is always in pending scope.perform_microtask_checkpoint(); i tried running this as well.

calling a javascript function and waiting for the promise with `rusty_v8`

if i make the above js function sync (just removing the async) then the whole thing works, i get the result string "helloworld" out. so the function call works.

this main function is being called from rust

    let result = function.call(scope, recv, &[]).expect("couldnt run");

    let result = function.call(scope, recv, &[]).expect("couldnt run");

calling a javascript function and waiting for the promise with `rusty_v8`

it was

async function main() {
return "helloworld"
}

async function main() {
return "helloworld"
}

yea!, thats what is puzzling me. promise.state() is Pending, i tried pumping the loop as well in a while loop

    while v8::Platform::pump_message_loop(&v8::V8::get_current_platform(), scope, false) {
    //     do nothing
    }

    while v8::Platform::pump_message_loop(&v8::V8::get_current_platform(), scope, false) {
    //     do nothing
    }

i am using rusty_v8. But i am unsure how to handle the event loop here. is it possible to get the value synchronously? or do you have any examples which i can refer to? i have the result: Local<Value> which is a promise (result.is_promise is true). what i am trying to do is let value = get_inner_value_synchronously(result) . is this possible?
