Struct HashEmbedder 

pub struct HashEmbedder { /* private fields */ }

A deterministic feature-hashing embedder.

Implementations

impl HashEmbedder

pub fn new(dim: usize) -> Self

Create a dim-dimensional hash embedder with default n-gram and seed.

pub fn with_params(dim: usize, ngram: u8, seed: u64) -> Self

Create with explicit parameters. All three are folded into the EmbedderId, so changing any of them invalidates an old index.

Trait Implementations

impl Clone for HashEmbedder

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HashEmbedder

impl Debug for HashEmbedder

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

Formats the value using the given formatter.

impl Embedder for HashEmbedder

type EmbedFuture<'a> = Ready<Result<(), Error>>

The future returned by Embedder::embed_batch.

fn dim(&self) -> usize

The embedding dimension.

fn metric(&self) -> Metric

The metric the produced vectors are intended for.

fn identity(&self) -> EmbedderId

This embedder’s stable identity.

fn embed_batch<'a>( &'a self, texts: &'a [&'a str], out: &'a mut [f32], ) -> Self::EmbedFuture<'a>

Embed texts into out (texts.len() * dim floats, row-major).
