Struct QueryResult 

pub struct QueryResult {
    pub rows: Vec<QueryRow>,
    pub rows_affected: u64,
    pub execution_time_ms: u64,
    pub metadata: QueryMetadata,
}

Query result containing rows and metadata

Fields

rows: Vec<QueryRow>

Result rows

rows_affected: u64

Number of rows affected (for INSERT/UPDATE/DELETE)

execution_time_ms: u64

Query execution time in milliseconds

metadata: QueryMetadata

Query metadata

Implementations

impl QueryResult

pub fn new() -> Self

Create a new empty query result

pub fn with_rows(rows: Vec<QueryRow>) -> Self

Create a result with rows

pub fn with_affected_rows(rows_affected: u64) -> Self

Create a result for DML operations (INSERT/UPDATE/DELETE)

pub fn row_count(&self) -> usize

Get the number of rows in the result

pub fn is_empty(&self) -> bool

Check if the result is empty

pub fn get_row(&self, index: usize) -> Option<&QueryRow>

Get a specific row by index

pub fn columns(&self) -> &[ColumnInfo]

Get column information

pub fn column_names(&self) -> Vec<String>

Get column names

pub fn execution_time(&self) -> u64

Get execution time in milliseconds

pub fn performance(&self) -> &PerformanceMetrics

Get performance metrics

pub fn warnings(&self) -> &[String]

Get warnings

pub fn add_warning(&mut self, warning: String)

Add a warning

pub fn to_json(&self) -> Value

Convert to JSON representation

Note: execution_time_ms is intentionally excluded to keep snapshot output deterministic; use execution_time() to read it separately.

pub fn iter(&self) -> Iter<'_, QueryRow>

Create result iterator
