Trait for embedding generation

Required Methods

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

Embed a single text

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

Batch embed multiple texts

fn dimension(&self) -> usize

Get embedding dimension

fn model_id(&self) -> &str

Get model identifier

Provided Methods

fn embed_query(&self, query: &str) -> Result<Vec<f32>>

Embed a query (may use query prefix)

fn embed_document(&self, document: &str) -> Result<Vec<f32>>

Embed a document (may use document prefix)

fn embed_chunks(&self, chunks: &mut [Chunk]) -> Result<()>

Embed chunks and update them in place

Trait Implementations

impl Embedder for Box<dyn Embedder>

Blanket impl so HybridRetriever<Box<dyn Embedder>> works without requiring the caller to know the concrete embedder type at compile time.

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

Embed a single text

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

Batch embed multiple texts

fn dimension(&self) -> usize

Get embedding dimension

fn model_id(&self) -> &str

Get model identifier

fn embed_query(&self, query: &str) -> Result<Vec<f32>>

Embed a query (may use query prefix)

fn embed_document(&self, document: &str) -> Result<Vec<f32>>

Embed a document (may use document prefix)

fn embed_chunks(&self, chunks: &mut [Chunk]) -> Result<()>

Embed chunks and update them in place

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
