Trait Embedder 

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

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

Trait for text embedding backends.

Implementations convert text strings into dense vector representations suitable for semantic similarity search.

Required Methods

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

Embed a single text string into a vector.

fn dimension(&self) -> usize

Return the dimensionality of the output embedding vectors.

Provided Methods

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

Embed a batch of text strings into vectors.

Default implementation calls embed for each text sequentially. Backends should override this for batch-optimized inference.

Trait Implementations

impl Embedder for Box<dyn Embedder>

Blanket implementation for boxed trait objects.

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