[Boost-users] circular_buffer: rotate() vs erase_begin() for scalars

I'm using circular_buffer to represent a FIFO queue of bytes: boost::circular_bufferstd::uint8_t m_queue; When I read bytes from the "front", I simply do: m_queue.erase_begin(num_read_bytes); I do so because the documentation for erase_begin() specifically mentions constant time performance for scalar types since no destructor needs to be called. However, I feel that rotate() better expresses what I'm trying to do. Is there a reason to prefer one over the other for scalar types?
