Hi All,

I've just released DRoaring, a D library which wraps CRoaring: https://github.com/RoaringBitmap/CRoaring

Roaring Bitmaps are compressed bit arrays which can store a huge amount of bits in a space efficient manner. The bitmap is organized so that adding/removing bits is very fast and don't require unpacking the whole bitmap. You can use bit arrays for efficient set operations.
