Struct finalfusion::subword::HashIndexer

pub struct HashIndexer<H> { /* fields omitted */ }

Indexer using a hash function.

This indexer first hashes a given n-gram and then maps the resulting hash into 2^buckets_exp buckets.

The largest possible bucket exponent is 64.

Trait Implementations

impl<H> Indexer for HashIndexer<H> where
    H: Default + Hasher, 

fn index_ngram(&self, ngram: &StrWithCharLen) -> u64

Map an n-gram to an index in the subword embedding matrix.

impl<H> BucketIndexer for HashIndexer<H> where
    H: Default + Hasher, 

fn new(buckets_exp: usize) -> Self

The largest possible bucket exponent is 64.

fn buckets(&self) -> usize

Get the number of buckets.

impl<H> Copy for HashIndexer<H>

impl<H> Clone for HashIndexer<H>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H> PartialEq<HashIndexer<H>> for HashIndexer<H>

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

This method tests for self and other values to be equal, and is used by ==.
