Struct IdentityReranker 

pub struct IdentityReranker;

No-op Reranker: returns the first top_k candidates in the order the underlying VectorStore produced them, copying the retrieval score into RerankedDocument::rerank_score so downstream consumers see a uniform shape.

Trait Implementations

impl Clone for IdentityReranker

fn clone(&self) -> IdentityReranker

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IdentityReranker

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

Formats the value using the given formatter.

impl Default for IdentityReranker

fn default() -> IdentityReranker

Returns the “default value” for a type.

impl Reranker for IdentityReranker

fn rerank<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _query: &'life1 str, candidates: Vec<Document>, top_k: usize, _ctx: &'life2 ExecutionContext, ) -> Pin<Box<dyn Future<Output = Result<Vec<RerankedDocument>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Re-order (and optionally trim) the candidate list, attaching a reranker-specific score to each survivor. The returned Vec MUST contain only documents from the input candidates — rerankers cannot fabricate new content.
