Struct Embedding 

pub struct Embedding {
    pub vector: EmbeddingVector,
    pub dimensions: usize,
    pub model: String,
    pub source_id: String,
    pub metadata: HashMap<String, Value>,
    pub created_at: DateTime<Utc>,
}

A dense vector representation of text content with metadata

Embeddings are high-dimensional vectors that capture semantic meaning of text in a format suitable for similarity comparison and retrieval. Each embedding includes the vector data, source information, and generation metadata.

Example

use rrag::prelude::*;

let vector = vec![0.1, -0.2, 0.3, 0.4]; // 4-dimensional example
let embedding = Embedding::new(vector, "text-embedding-ada-002", "doc-123")
    .with_metadata("content_type", "paragraph".into())
    .with_metadata("language", "en".into());

assert_eq!(embedding.dimensions, 4);
assert_eq!(embedding.model, "text-embedding-ada-002");

Fields

vector: EmbeddingVector

The actual embedding vector

dimensions: usize

Dimensions of the embedding

model: String

Model used to generate this embedding

source_id: String

Source content identifier

metadata: HashMap<String, Value>

Embedding metadata

created_at: DateTime<Utc>

Generation timestamp

Implementations

impl Embedding

pub fn new( vector: EmbeddingVector, model: impl Into<String>, source_id: impl Into<String>, ) -> Self
