where
    F: Future,
{
    Future {
        future: F,
    },
    Result {
        result: Option<Result<F::Output, Box<dyn Any + Send + 'static>>>,
    },
}

Trait Implementations

impl<F: Future> FutureOrResult for TaskFuture<F>

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<()>

Poll the future. When the future is ready, this will return Poll::Ready(()), and the result call can be used to discover the result.

unsafe fn result( self: Pin<&mut Self>, out_value: *mut (), ) -> Option<Result<(), Box<dyn Any + Send + 'static>>>

Retrieve the result of the future. None is returned if the future has not been polled to completion, or if the result has already been retrieved. Some(()) indicates that the value has been written to the value pointer. Some(Err(e)) indicates the future panicked, and e is the panic value.
