Webstd::bitset Performs binary shift left (towards higher index positions) and binary shift right (towards lower index positions). Zeroes are shifted in, and bits that would go to an index out of range are dropped (ignored). 1-2) Performs binary shift left. The (2) version is destructive, i.e. performs the shift to the current object.
