Trait Embedder 

pub trait Embedder: Send + Sync {
    // Required methods
    fn dimension(&self) -> usize;
    fn embed(&self, text: &str) -> Result<Vec<f32>>;

    // Provided method
    fn embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>> { ... }
}

Trait for generating text embeddings.

Required Methods

fn dimension(&self) -> usize

Returns the embedding dimension.

fn embed(&self, text: &str) -> Result<Vec<f32>>

Generates an embedding vector for the given text.

Provided Methods

fn embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>>

Generates embedding vectors for multiple texts in a single call. The default implementation calls embed() in a loop; backends that support true batched inference (e.g. ONNX) override this for better throughput.

Implementors

impl Embedder for OnnxEmbedder

Available on crate feature real-embeddings only.
