Expand description

Backend-neutral embedding seam used by the store’s search implementation.

The deterministic lexical backend is always available. Higher-quality implementations may be injected through StoreHooks without changing the search interface or any transport.

Required Methods§

Source

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

Source

fn dim(&self) -> usize

Source

fn name(&self) -> &str

Provided Methods§

Source

fn is_semantic(&self) -> bool

Whether this backend ranks by meaning rather than by surface form.

Defaults to false: the claim is earned, never inherited. A backend that returns true is asserting it can rank a semantically related document above a lexically similar decoy, and conformance::audit_semantic_claim is the bar that assertion is measured against.

The default direction matters. Under-claiming costs a caller some recall it could have had; over-claiming makes SearchResponse::semantic_floor lie, silently converts a SearchMode::Semantic query into surface matching, and suppresses the fallback notice that would otherwise tell the caller what happened. So an unconsidered backend degrades loudly instead of claiming quietly.

Source

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

Dyn Compatibility§

This trait is dyn compatible.

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