SyncChannel<T> can move 'T: !Send' to other threads
Affected versions of this crate unconditionally implement Send/Sync for SyncChannel<T>
. SyncChannel<T>
doesn't provide access to &T
but merely serves as a channel that consumes and returns owned T
. Users can create UB in safe Rust by sending T: !Send
to other threads with SyncChannel::send/recv
APIs. Using T = Arc<Cell<_>
allows to create data races (which can lead to memory corruption), and using T = MutexGuard<T>
allows to unlock a mutex from a thread that didn't lock the mutex.
