Enum RetrievalStage 

pub enum RetrievalStage {
    Lexical,
    SymbolScore,
    DenseRetrieval,
    Rerank,
    GraphExpand,
}

Describes a stage in the retrieval pipeline.

The full pipeline is: Lexical → SymbolScore → DenseRetrieval → Rerank → GraphExpand

Each stage can be enabled/disabled and contributes a weighted score.

Variants

Lexical

FTS5 / BM25 corpus search — file-level pre-filtering.

SymbolScore

Symbol name/signature scoring — AST-aware matching.

DenseRetrieval

Embedding-based dense retrieval — semantic similarity.

Rerank

Multi-signal blending — text + pagerank + recency + semantic.

GraphExpand

Graph expansion — callers, importers, type hierarchy of top results.

Trait Implementations

impl Clone for RetrievalStage

fn clone(&self) -> RetrievalStage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetrievalStage

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

Formats the value using the given formatter.

impl PartialEq for RetrievalStage

fn eq(&self, other: &RetrievalStage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RetrievalStage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
