Struct MultiVectorEmbedding 

pub struct MultiVectorEmbedding {
    pub token_vectors: Vec<Vec<f32>>,
}

ColBERT-style multi-vector representation (per-token embeddings).

Each inner vector is the embedding of a single token. Used for late interaction scoring via MaxSim.

Fields

token_vectors: Vec<Vec<f32>>

Per-token embedding vectors.

Implementations

impl MultiVectorEmbedding

pub fn from_dense_chunked(vec: &[f32], num_tokens: usize) -> Self

Build a multi-vector representation by chunking a dense vector into num_tokens roughly-equal sub-vectors.

Each sub-vector acts as a pseudo per-token embedding. When native per-token embeddings are available from the model, use MultiVectorEmbedding::from_token_vectors instead.

pub fn from_token_vectors(token_vectors: Vec<Vec<f32>>) -> Self

Build directly from pre-computed per-token embedding vectors.

pub fn len(&self) -> usize

Number of token vectors.

pub fn is_empty(&self) -> bool

Whether the multi-vector is empty.

Trait Implementations

impl Clone for MultiVectorEmbedding

fn clone(&self) -> MultiVectorEmbedding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiVectorEmbedding

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

Formats the value using the given formatter.

impl PartialEq for MultiVectorEmbedding

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