Struct HammingHasher

pub struct HammingHasher<const B: usize, const H: usize> { /* private fields */ }

This structure allows one to generate balanced locality-sensitive hashes.

B is the number of bytes in the codewords. H is the number of bytes in the hash.

Implementations

impl<const B: usize, const H: usize> HammingHasher<B, H>

pub fn new() -> Self

pub fn new_with_seed(seed: u64) -> Self

pub fn new_with_codewords(codewords: Vec<BitArray<B>>) -> Self

There must be exactly H * 8 codewords.

pub fn hash(&self, feature: &BitArray<B>) -> BitArray<H>

Convert the input feature into a hash.

pub fn hash_bag<'a>( &self, features: impl IntoIterator<Item = &'a BitArray<B>>, ) -> BitArray<H>

Convert the input features into a hash.
