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);
