Trait Embedder 

pub trait Embedder: Send + Sync {
    // Required methods
    fn embed<'life0, 'life1, 'async_trait>(
        &'life0 self,
        texts: &'life1 [String],
    ) -> Pin<Box<dyn Future<Output = Result<Vec<Vec<f32>>>> + Send + 'async_trait>>
       where Self: 'async_trait,

    fn dimensions(&self) -> usize;
}

Trait for text embedding models.

Implementations must be Send + Sync to allow sharing across async tasks via Arc<dyn Embedder>.

Required Methods

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

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

Embed one or more texts into fixed-dimensional vectors.

Returns one vector per input text. All vectors have the same dimensionality (see dimensions).

fn dimensions(&self) -> usize

Dimensionality of the output vectors (e.g., 384 for BGE-Small-EN).
