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

extern crate bloom_filter;

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");
    }
}
