Function stakker_async_await::future_pull_result

pub fn future_pull_result<T>(
    core: &mut Core, 
    ret: Ret<Ret<T>>
) -> impl Future<Output = Result<T, ActorFail>>

Create a pull-style Ret → Future pipe, that passes through failure

This returns a future which when polled will send a message to the provided stakker::Ret instance in order to request a value. So it “pulls” the value only on demand. The provided stakker::Ret instance is given a stakker::Ret to use to send back the value. If the value is not provided, either because there is nothing left running to handle the stakker::Ret sent, or if the provided stakker::Ret is dropped, then the future resolves to None. If a value is passed through then it resolves to Some(value). To ignore None values and drop the task, see future_pull_some.
