Struct Embedding 

pub struct Embedding {
    pub vector: Vec<f32>,
    pub usage: Option<EmbeddingUsage>,
}

One embedded text’s vector plus optional usage metadata.

usage is None when the backend does not surface token accounting (in-process stub embedders, hash-based encoders). Cost-aware backends (OpenAI, Voyage, Cohere) return Some so downstream meters can charge per call.

Fields

vector: Vec<f32>

The encoded vector. Length always equals Embedder::dimension.

usage: Option<EmbeddingUsage>

Token-accounting metadata when the backend reports it.

Implementations

impl Embedding

pub const fn new(vector: Vec<f32>) -> Self

Build an embedding with no usage metadata. Stub backends and tests use this when they have no token count to report.

pub const fn with_usage(self, usage: EmbeddingUsage) -> Self

Builder-style usage attachment.

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: &Embedding) -> 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.
