Expand description

Abstract embedding provider.

Uses #[async_trait] to keep the trait object-safe (i.e. usable as Box<dyn Embedder>) while allowing async fn syntax.

fn is_semantic(&self) -> bool

Whether this embedder produces semantically meaningful vectors. Defaults to true so real embedding providers don’t have to opt in; lexical-only fallbacks override to false so hybrid retrieval knows to lean harder on the FTS baseline for keyword-heavy queries.
