Re: [Boost-users] tuple memory alignment

I noticed that having a std::vector containing boost::tuple elements has "dense" memory layout.

std::vector is guaranteed to layout data as a contiguous array of its elements, i.e., for a vector v of size k (parantheses added for clarity), ( &( v[0] ) )[m] points to v[m] for m less than k. I don't know a tuple could guarantee that its elements are stored in same way as a C struct. Regards, Ravi
