Bloom Filter

An implementation of a bloom filter as as described in [Space/Time Trade-offs in Hash Coding with Allowable Errors] (http://dmod.eu/deca/ft_gateway.cfm.pdf).

Example

``` rust,norun extern crate bloomfilter;

use bloom_filter::BloomBuilder;

fn main() { let elements = 2u64.pow(20); let fpr = 0.01; let mut bloom = BloomBuilder::new(elements).with_fpr(fpr).finish().unwrap();

bloom.insert("foo");
bloom.insert("bar");
bloom.insert("baz");

if bloom.lookup("foo") {
    println!("found foo in the bloom filter");
}

} ```
