Struct Embedding 

pub struct Embedding {
    pub vector: Vec<f32>,
    pub text_hash: u64,
}

A single embedding vector with metadata.

Fields

vector: Vec<f32>

The embedding vector (normalized to unit length).

text_hash: u64

Hash of the original text for cache lookups.

Implementations

impl Embedding

pub fn new(vector: Vec<f32>, text_hash: u64) -> Self

Create a new embedding from a vector. Automatically normalizes the vector to unit length.

pub fn from_normalized(vector: Vec<f32>, text_hash: u64) -> Self

Create an embedding without normalizing (assumes already normalized).

pub fn dimensions(&self) -> usize

Get the dimensionality of this embedding.

pub fn cosine_similarity(&self, other: &Embedding) -> f32

Cosine similarity with another embedding. For normalized vectors, this equals the dot product.

pub fn dot_product(&self, other: &Embedding) -> f32

Dot product (for pre-normalized vectors, equals cosine similarity).

pub fn euclidean_distance(&self, other: &Embedding) -> f32

Euclidean distance to another embedding.

pub fn norm(&self) -> f32

L2 norm of the vector.

pub fn is_normalized(&self) -> bool

Check if this embedding is normalized (unit length).

Trait Implementations

impl Clone for Embedding

fn clone(&self) -> Embedding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Embedding

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Embedding

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Embedding

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

impl Serialize for Embedding

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
