Boolean arrays compressed into integers. Useful for storing boolean arrays in databases with just a single integer.

use smolmask::BoolArray;

fn main() {
    let bools = vec![true, false, true, true];
    let integer: u64 = BoolArray::store(&bools).unwrap();
    println!("Integer: {}", integer); // 1096635
    println!("Length: {}", BoolArray::length(integer)); // 4
    println!("{:?}", BoolArray::retrieve(integer)); // [true, false, true, true]
}
