Trait for generating text embeddings

Required Methods

fn name(&self) -> &str

Provider name for logging

fn dimension(&self) -> usize

Embedding dimension (e.g., 1536 for OpenAI text-embedding-3-small)

fn embed<'life0, 'life1, 'async_trait>( &'life0 self, text: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Embedding>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Generate embedding for a single text

Provided Methods

fn embed_batch<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, texts: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Result<Vec<Embedding>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Generate embeddings for multiple texts (batch)

Default implementation calls embed() sequentially.
