Struct FacetVectorOperator 

pub struct FacetVectorOperator {
    pub facet_field: String,
    pub vector_op: VectorSimilarityOperator,
    pub source: Option<Arc<dyn Operator>>,
}

Facet counts conditioned on vector similarity. Output rows are synthetic posting entries — doc_id is a positional placeholder, payload.score is the bucket count, and payload.fields carries the _facet_field / _facet_value / _facet_count triple.

Fields

facet_field: String

vector_op: VectorSimilarityOperator

source: Option<Arc<dyn Operator>>

Implementations

impl FacetVectorOperator

pub fn new( facet_field: impl Into<String>, query_vector: Vec<f32>, threshold: f32, source: Option<Arc<dyn Operator>>, ) -> Self
