C++ makes it very inconvenient to make uninitialized space in a std::vector to read bytes into with I/O, but copying one T at a time with .push_back from a new buffer is almost certainly worse than just growing and letting a stupid compiler zero the bytes unnecessarily, then reading into that space. At best this copy loop will optimize to a call to memcpy, but maybe not with the growth check and possible reallocation after some data-dependent number of elements copied.
