Struct RerankCandidate 

pub struct RerankCandidate {
    pub id: Vec<u8>,
    pub text: String,
    pub score: f32,
    pub metadata: Value,
}

One pre-rerank candidate. The operator hydrates the chunk text BEFORE calling the reranker (see lunaris_retrieve::hydrate::partial_hydrate_text) so the cross-encoder can pair-encode (query, doc.text) for scoring.

score is the upstream operator’s score — the reranker REPLACES this with its own logit so downstream .top(n) ranks by cross-encoder relevance.

Fields

id: Vec<u8>

Backend-issued id (the same id bytes that came from the upstream RawHit).

text: String

Chunk body — required for cross-encoder pair scoring. Empty string is allowed (the model will produce a low score, the cull is downstream).

score: f32

Upstream operator’s score. The reranker REPLACES this with its own logit on return.

metadata: Value

Free-form metadata carried from the upstream RawHit; the reranker passes it through unchanged.
