Function croaring_sys::roaring_bitmap_jaccard_index

pub unsafe extern "C" fn roaring_bitmap_jaccard_index(
    x1: *const roaring_bitmap_t, 
    x2: *const roaring_bitmap_t
) -> f64

Computes the Jaccard index between two bitmaps. (Also known as the Tanimoto distance, or the Jaccard similarity coefficient)

The Jaccard index is undefined if both bitmaps are empty.
