Cross-encoder trait for reranking retrieved results

Required Methods

fn rerank<'life0, 'life1, 'async_trait>( &'life0 self, query: &'life1 str, candidates: Vec<SearchResult>, ) -> Pin<Box<dyn Future<Output = Result<Vec<RankedResult>>> + Send + 'async_trait>>

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

Rerank a list of search results based on relevance to query

fn score_pair<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, query: &'life1 str, document: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<f32>> + Send + 'async_trait>>

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

Score a single query-document pair

fn score_batch<'life0, 'async_trait>( &'life0 self, pairs: Vec<(String, String)>, ) -> Pin<Box<dyn Future<Output = Result<Vec<f32>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Batch score multiple query-document pairs
