I figured out how to easily load all vectors with memory mapping (will implement in another PR), so I'm only gonna keep here the constructor for sd_vector with streaming. |

SD vector with the vector of the least significant bits of set bits' positions stored on disk.$\approx 2$ bits of RAM per set bit. The remaining $\lceil \log_2 n\rceil - \lceil \log_2 m\rceil$ bits are stored on disk.

Run benchmarks:
Results:
m_low in int_vector_buffer:
m_low in int_vector_mapper:
m_low and m_high in int_vector_mapper:
all with mmap:
all in RAM:
The times fluctuate quite a bit, it would be good to also benchmark it on the cluster.
