Struct DummyEmbedder 

pub struct DummyEmbedder;

👎Deprecated since 3.11.0:

renamed to NonRankingEmbedder — the old name did not say that recall is unranked

Legacy name for NonRankingEmbedder. Deprecated at its definition, so downstream use warns; #[deprecated] on a re-export is silently ignored by rustc and would announce a migration it never prompts. Legacy name for NonRankingEmbedder, behaving identically.

A separate unit struct rather than pub use NonRankingEmbedder as DummyEmbedder, because rustc silently ignores #[deprecated] on a re-export: downstream code kept compiling with no warning at all, so the alias would have announced a migration it never actually prompted. A real deprecated item warns in both type and value position, which is what Arc::new(DummyEmbedder) call sites need.

Trait Implementations

impl Embedder for DummyEmbedder

fn dimension(&self) -> usize

Embedding dimensionality. Must be constant for a given Embedder instance — long-term memory backends reject vectors of the wrong length at runtime.

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

where 'life0: 'async_trait, 'life1: 'async_trait, DummyEmbedder: 'async_trait,

Compute one embedding per input text.

fn is_ranking(&self) -> bool

Whether distinct inputs produce distinct directions, i.e. whether a vector store wired with this embedder actually ranks by relevance.
