Struct QueryResult 

pub struct QueryResult {
    pub chunks: Vec<DataChunk>,
    pub num_rows: usize,
    pub num_columns: usize,
    pub success: bool,
    pub error_message: Option<String>,
    pub message: Option<String>,
    pub summary: Option<QuerySummary>,
}

The result of executing a Cypher query.

Contains result chunks as column-major DataChunk vectors, metadata (row/column counts), and optional timing summary.

Examples

let result = conn.query("MATCH (n) RETURN n LIMIT 5")?;
println!("Rows: {}, Columns: {}", result.num_rows, result.num_columns);
for chunk in &result.chunks {
    for field_idx in 0..chunk.fields.len() {
        for row in 0..chunk.size {
            if let Some(val) = chunk.get_value(field_idx, row) {
                println!("  {:?}", val);
            }
        }
    }
}

Fields

chunks: Vec<DataChunk>

num_rows: usize

num_columns: usize

success: bool

error_message: Option<String>

message: Option<String>

Human-readable message (e.g. “Table created” for DDL).

summary: Option<QuerySummary>

Timing summary for the query.

Implementations

impl QueryResult

pub fn new(chunks: Vec<DataChunk>) -> Self

pub fn success_message(msg: String) -> Self

pub fn with_summary(self, summary: QuerySummary) -> Self

Attach timing summary to this result.

pub fn error(msg: String) -> Self

pub fn is_success(&self) -> bool

pub fn num_rows(&self) -> usize

pub fn num_columns(&self) -> usize

pub fn result_summary(&self) -> String

Get a human-readable summary of the result.
