Description:
As the
ProgramData.varsis re-allocated lots of time, we can reducememmoveoperations by boxing theVarUsageInfo. This is because the hash map would need to allocate, e.g.,1024 * size_of<Box<T>>instead of1024 * size_of<VarUsageInfo>while incrementing the size of the hash map from 512 to 1024.
