Struct DimReduceEmbedder 

pub struct DimReduceEmbedder { /* private fields */ }

MRL dimension reduction wrapper.

Implementations

impl DimReduceEmbedder

pub fn new(inner: Arc<dyn Embedder>, target_dim: usize) -> SearchResult<Self>

Create a dimension-reduced view of an embedder.

Errors

Returns SearchError::InvalidConfig when requested dimension is invalid.

Trait Implementations

impl Debug for DimReduceEmbedder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Embedder for DimReduceEmbedder

fn embed<'a>(&'a self, cx: &'a Cx, text: &'a str) -> SearchFuture<'a, Vec<f32>>

Embed a single text string into a vector of f32 floats.

fn embed_batch<'a>( &'a self, cx: &'a Cx, texts: &'a [&'a str], ) -> SearchFuture<'a, Vec<Vec<f32>>>

Embed a batch of text strings.

fn dimension(&self) -> usize

The dimensionality of embedding vectors produced by this model.

fn id(&self) -> &str

A unique, stable identifier for this embedder.

fn model_name(&self) -> &str

Human-readable model name.

fn is_ready(&self) -> bool

Whether this embedder is loaded and operational.

fn is_semantic(&self) -> bool

Whether this embedder produces semantically meaningful vectors.

fn category(&self) -> ModelCategory

The speed/quality category of this embedder.

fn tier(&self) -> ModelTier

Default progressive tier assignment.

fn supports_mrl(&self) -> bool
