Struct BloomFilterHeader

pub struct BloomFilterHeader {
    pub num_bytes: i32,
    pub algorithm: BloomFilterAlgorithm,
    pub hash: BloomFilterHash,
    pub compression: BloomFilterCompression,
}

Bloom filter header is stored at beginning of Bloom filter data of each column and followed by its bitset.

Fields

num_bytes: i32

The size of bitset in bytes

algorithm: BloomFilterAlgorithm

The algorithm for setting bits.

hash: BloomFilterHash

The hash function used for Bloom filter

compression: BloomFilterCompression

The compression used in the Bloom filter

Trait Implementations

impl Clone for BloomFilterHeader

fn clone(&self) -> BloomFilterHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BloomFilterHeader

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

Formats the value using the given formatter.

impl PartialEq for BloomFilterHeader

fn eq(&self, other: &BloomFilterHeader) -> 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.
