croaring-rs
A Rust wrapper for CRoaring (a C/C++ implementation at https://github.com/RoaringBitmap/CRoaring)
The original java version can be found at https://github.com/RoaringBitmap/RoaringBitmap
Usage example
use croaring::Bitmap;
let mut rb1 = Bitmap::create();
rb1.add(1);
rb1.add(2);
rb1.add(3);
rb1.add(4);
rb1.add(5);
rb1.add(100);
rb1.add(1000);
rb1.run_optimize();
let mut rb2 = Bitmap::create();
rb2.add(3);
rb2.add(4);
rb2.add(1000);
rb2.run_optimize();
let mut rb3 = Bitmap::create();
assert_eq!(rb1.cardinality(), 7);
assert!(rb1.contains(3));
rb1.and_inplace(&rb2);
rb3.add(5);
rb3.or_inplace(&rb1);
let mut rb4 = Bitmap::fast_or(&[&rb1, &rb2, &rb3]);
rb1.and_inplace(&rb2);
println!("{:?}", rb1);
rb3.add(5);
rb3.or_inplace(&rb1);
println!("{:?}", rb1);
rb3.add(5);
rb3.or_inplace(&rb1);
println!("{:?}", rb3.to_vec());
println!("{:?}", rb3);
println!("{:?}", rb4);
rb4 = Bitmap::fast_or(&[&rb1, &rb2, &rb3]);
println!("{:?}", rb4);
