Expand description
Computing the same thing each frame can be expensive, so often you want to save the result from the previous frame and reuse it.
Enter FrameCache: it caches the results of a computation for one frame.
If it is still used next frame, it is not recomputed.
If it is not used next frame, it is evicted from the cache to save memory.
Structs
