Struct Bloom 

pub struct Bloom { /* private fields */ }

The filter over a set of keys.

Implementations

impl Bloom

pub fn build<K: AsRef<[u8]>>(keys: &[K], bits_per_key: usize) -> Self

A filter over keys at bits_per_key; at least one block.

pub fn contains(&self, key: &[u8]) -> bool

Whether key may be in the set: never false for a key that is, true for about 1 percent of keys that are not.

pub fn blocks(&self) -> usize

Blocks in the filter.

pub fn to_bytes(&self) -> Vec<u8>

The filter as bytes: each word little-endian, blocks in order.

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

The filter to_bytes wrote; refused unless whole blocks, at least one.

Trait Implementations

impl Clone for Bloom

fn clone(&self) -> Bloom

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Bloom

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Bloom

fn eq(&self, other: &Bloom) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
