Once in a while, the circumstances allow to use the goes-to operator…

            uint32_t log2 = (run_length <= 256)
                ? constant::LOG2[run_length - 1]
                : (31 - __builtin_clz(run_length));
            if(dst_idx >= count - log2)
                { res = false; break; }
            while(log2 --> 0) // The famous "goes to" operator.
                dst[dst_idx++] = (run_length >> log2) & 1;
            continue;
