Struct QueryResult 

pub struct QueryResult {
    pub nodes: Vec<u64>,
    pub scores: Vec<f32>,
    pub embeddings: Option<Vec<Vec<f32>>>,
    pub attention_weights: Option<Vec<Vec<f32>>>,
    pub subgraph: Option<SubGraph>,
    pub latency_ms: u64,
}

Query result with nodes, scores, and optional metadata

Fields

nodes: Vec<u64>

Matched node IDs

scores: Vec<f32>

Similarity scores (higher = more similar)

embeddings: Option<Vec<Vec<f32>>>

Optional node embeddings after GNN processing

attention_weights: Option<Vec<Vec<f32>>>

Optional attention weights from differentiable search

subgraph: Option<SubGraph>

Optional subgraph extraction

latency_ms: u64

Query latency in milliseconds

Implementations

impl QueryResult

pub fn new() -> Self

Create a new empty query result

pub fn with_nodes(nodes: Vec<u64>, scores: Vec<f32>) -> Self

Create query result with nodes and scores

Arguments

• nodes - Node IDs
• scores - Similarity scores

Example

use ruvector_gnn::query::QueryResult;

let result = QueryResult::with_nodes(vec![1, 2, 3], vec![0.9, 0.8, 0.7]);
assert_eq!(result.nodes.len(), 3);

pub fn with_embeddings(self, embeddings: Vec<Vec<f32>>) -> Self

Add embeddings to the result

pub fn with_attention(self, attention: Vec<Vec<f32>>) -> Self

Add attention weights to the result

pub fn with_subgraph(self, subgraph: SubGraph) -> Self

Add subgraph to the result

pub fn with_latency(self, latency_ms: u64) -> Self

Set query latency

pub fn len(&self) -> usize

Get number of results

pub fn is_empty(&self) -> bool

Check if result is empty

pub fn top_k(&self, k: usize) -> Self

Get top-k results

pub fn best(&self) -> Option<(u64, f32)>

Get the best result (highest score)

pub fn filter_by_score(self, min_score: f32) -> Self

Filter results by minimum score
