11122,Bulk/Range set/unset operations,gonzalobg88@…,jsiek,"I need to set/unset a subrange of the elements within a dynamic bitset. The current best way (that I know of) of doing this, is assigning a value to each element individually. 

This is far from optimal, since an optimal solution would iterate over the blocks, setting the value once for each block. It is also non-trivial to work around this, since one needs to consider that the sub-range might being and end in the middle of some block. 

I propose to add the following two overloads to the set and unset member functions, to allow for this use case:

std::size_t set(std::size_t from, std::size_t to, bool value);
std::size_t unset(std::size_t from, std::size_t to, bool value);
// (maybe range-based and iterator-based versions should be added as well)

I'm willing to implement, test, and document this. But want to discuss before:

What do you think? Is there a better solution to this problem that is both safe and efficient?",Feature Requests,new,To Be Determined,dynamic_bitset,Boost Development Trunk,Problem,,,
