An embedder turns text into a fixed-dimension vector.

Implementations must produce vectors of Embedder::dim length on every call; the storage layer validates and rejects mismatches.

Required Methods

fn dim(&self) -> usize

Vector dimensionality.

fn model_name(&self) -> &str

Stable model identifier (e.g., "bge-small-en-v1.5").

fn embed<'life0, 'life1, 'async_trait>( &'life0 self, text: &'life1 str, ) -> Pin<Box<dyn Future<Output = EmbedResult<Vec<f32>>> + Send + 'async_trait>>

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

Embed one piece of text.

Provided Methods

fn embed_batch<'life0, 'life1, 'async_trait>( &'life0 self, texts: &'life1 [String], ) -> Pin<Box<dyn Future<Output = EmbedResult<Vec<Vec<f32>>>> + Send + 'async_trait>>

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

Embed a batch of texts. Default implementation calls embed sequentially; production embedders should override for batching.

Dyn Compatibility

This trait is dyn compatible.

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