测试用例

```rust use bloomfilterplus::*;

fn main() { // test 1 let filter = BloomFilter::new(); filter.insert("key").unwrap(); filter.debug(); asserteq!(true, filter.contains("key").unwrap()); asserteq!(false, filter.contains("key1").unwrap()); filter.savetofile("test.bitmap").unwrap();

let filter_2 = BloomFilter::new();
filter_2.load_file("test.bitmap").unwrap();
println!("");
filter_2.debug();
assert_eq!(true, filter_2.contains("key").unwrap());
assert_eq!(false, filter_2.contains("key1").unwrap());

// // test2
let filter3 = BloomFilter::new();
filter3.set_size(1024);
filter3.insert("key").unwrap();
filter3.debug();
assert_eq!(true, filter3.contains("key").unwrap());
assert_eq!(false, filter3.contains("key1").unwrap());

}
