Struct Embedding 

pub struct Embedding(/* private fields */);

A vector with two explicit construction policies.

Embedding::from_raw truncates and L2-normalises model output; Embedding::from_preserved validates nonempty, finite input and preserves every component’s bits without truncation or normalization. A zero vector remains zero and reports normalized() == false. Derived deserialization retains its existing, unvalidated behavior.

Implementations

impl Embedding

pub fn from_raw(raw: Vec<f32>, dim: Dimension) -> Result<Embedding, Error>

Truncate a raw model output to dim leading components, then L2-normalise.

Normalising after truncation matters: a slice of a unit vector is not unit length, and skipping this silently degrades ranking.

pub fn from_preserved(values: Vec<f32>) -> Result<Embedding, Error>

Restore a nonempty, finite vector without truncating or normalizing it. Every component’s bits are preserved, including signed zero and subnormals.

pub fn as_slice(&self) -> &[f32]

pub fn dim(&self) -> usize

pub fn dimension(&self) -> usize

Width derived from the vector, never duplicated mutable metadata.

pub fn normalized(&self) -> bool

Whether this vector has unit L2 norm (within 1e-5).

pub fn into_vec(self) -> Vec<f32>

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

Raw dot product, equal to cosine similarity only when both embeddings are L2-normalised. This method does not normalise either operand; deserialised, unnormalised vectors therefore give non-cosine values.
