BloomFilter

Implementations

impl BloomFilter[src]

pub fn new() -> Self[src]

create bloomfilter

example

test 1
let mut filter = BloomFilter::new();
filter.insert("key");
assert_eq!(true, filter.contains("key"));
assert_eq!(false, filter.contains("key1"));
// test2
let mut filter2 = BloomFilter::new().set_size(10);
filter2.insert("key");
assert_eq!(true, filter2.contains("key"));
assert_eq!(false, filter2.contains("key1"));

pub fn set_size(self, size: usize) -> Self[src]

Set the bitmap size, the data in the bitmap needs to be empty

example

// test2

let mut filter2 = BloomFilter::new().set_size(10);
filter2.insert("key");
assert_eq!(true, filter2.contains("key"));
assert_eq!(false, filter2.contains("key1"));

pub fn set_hash_loop(self, hash_loop: usize) -> Self[src]

Set the bit occupied by each data

example

// test2

let mut filter2 = BloomFilter::new().set_size(10);
filter2.insert("key");
assert_eq!(true, filter2.contains("key"));
assert_eq!(false, filter2.contains("key1"));

pub fn insert(&mut self, key: &str)[src]

add key to bloomfilter

example

// test2

let mut filter2 = BloomFilter::new().set_size(10);
filter2.insert("key");
assert_eq!(true, filter2.contains("key"));
assert_eq!(false, filter2.contains("key1"));

pub fn contains(&self, key: &str) -> bool[src]

Check whether the bloomfilter has key

example

// test2

let mut filter2 = BloomFilter::new().set_size(10);
filter2.insert("key");
assert_eq!(true, filter2.contains("key"));
assert_eq!(false, filter2.contains("key1"));

pub fn debug(&self)[src]

Binary print bitmap

example

let mut filter2 = BloomFilter::new().set_size(10);
filter2.insert("key");
assert_eq!(true, filter2.contains("key"));
assert_eq!(false, filter2.contains("key1"));
filter2.debug();
}

pub fn clear(&mut self)[src]

Reset Bitmap
