- Affected Functions
tokio::sync::oneshot channel is closed (via the
oneshot::Receiver::close method), a data race may occur if the
oneshot::Sender::send method is called while the corresponding
awaited or calling
When these methods are called concurrently on a closed channel, the two halves
of the channel can concurrently access a shared memory location, resulting in a
data race. This has been observed to cause memory corruption.
Note that the race only occurs when both halves of the channel are used
Receiver half has called
close. Code where
close is not used, or where the
Receiver is not
try_recv is not called after calling
is not affected.
