Struct Rank 

pub struct Rank {
    pub expr: Option<RankExpr>,
}

Wrapper for ranking expressions in search queries.

Contains an optional ranking expression. When None, results are returned in natural storage order without scoring.

Fields

• expr - The ranking expression (None = no ranking)

Examples

use chroma_types::operator::{Rank, RankExpr, QueryVector, Key};

// With ranking
let rank = Rank {
    expr: Some(RankExpr::Knn {
        query: QueryVector::Dense(vec![0.1, 0.2, 0.3]),
        key: Key::Embedding,
        limit: 100,
        default: None,
        return_rank: false,
    }),
};

// No ranking (natural order)
let rank = Rank {
    expr: None,
};

Fields

expr: Option<RankExpr>
