04:09:53  error[A001]: Data race when sending and receiving after closing a `oneshot` channel

04:09:53      = ID: RUSTSEC-2021-0124
04:09:53      = Advisory: https://rustsec.org/advisories/RUSTSEC-2021-0124
04:09:53      = If a `tokio::sync::oneshot` channel is closed (via the
04:09:53        [`oneshot::Receiver::close`] method), a data race may occur if the
04:09:53        `oneshot::Sender::send` method is called while the corresponding
04:09:53        `oneshot::Receiver` is `await`ed or calling `try_recv`.
04:09:53        
04:09:53        When these methods are called concurrently on a closed channel, the two halves
04:09:53        of the channel can concurrently access a shared memory location, resulting in a
04:09:53        data race. This has been observed to [cause memory corruption][corruption].
04:09:53        
04:09:53        Note that the race only occurs when **both** halves of the channel are used
04:09:53        after the `Receiver` half has called `close`. Code where `close` is not used, or where the
04:09:53        `Receiver` is not `await`ed and `try_recv` is not called after calling `close`,
04:09:53        is not affected.
04:09:53        
04:09:53        See [tokio#4225][issue] for more details.
