bit::vector — Join Bit-Vectors

Joins two or three arbitrary-sized bit-vectors to get one longer one.

template<std::unsigned_integral Block, typename Alloc>
constexpr bit::vector<Block, Alloc>
join(const bit::vector<Block, Alloc> &u,
     const bit::vector<Block, Alloc> &v);

template<std::unsigned_integral Block, typename Alloc>
constexpr bit::vector<Block, Alloc>
join(const bit::vector<Block, Alloc> &u,
     const bit::vector<Block, Alloc> &v,
     const bit::vector<Block, Alloc> &w);

Example

#include <bit/bit.h>
int main()
{
    auto u = bit::vector<>::ones(8);
    auto v = bit::vector<>::zeros(4);
    std::cout << u << " joined with " << v << " yields " << join(u, v) << '\n';
    std::cout << v << " joined with " << u << " yields " << join(v, u) << '\n';
}

Output

[1 1 1 1 1 1 1 1] joined with [0 0 0 0] yields [1 1 1 1 1 1 1 1 0 0 0 0]
[0 0 0 0] joined with [1 1 1 1 1 1 1 1] yields [0 0 0 0 1 1 1 1 1 1 1 1]
