rust-cache-padded 1.1.1 Prevent once piece of data invalidating other cached data

In concurrent programming, sometimes it is desirable to make sure commonly accessed shared data is not all placed into the same cache line. Updating an atomic value invalides the whole cache line it belongs to, which makes the next access to the same cache line slower for other CPU cores. Use CachePadded to ensure updating one piece of data doesn't invalidate other cached data.
