Struct ExecutorResult 

pub struct ExecutorResult { /* private fields */ }

Implementations

impl ExecutorResult

pub fn new(columns: Vec<String>, rows: RowVec) -> Self

Create a new memory result with columns and pooled rows

pub fn with_arc_columns(columns: CompactArc<Vec<String>>, rows: RowVec) -> Self

Create a new memory result with Arc columns (zero-copy)

pub fn with_shared_rows( columns: Vec<String>, rows: CompactArc<Vec<Row>>, ) -> Self

Create a new memory result with shared rows from cache (zero-copy for rows) This avoids cloning the entire Vec when reading from semantic cache

pub fn with_arc_columns_shared_rows( columns: CompactArc<Vec<String>>, rows: CompactArc<Vec<Row>>, ) -> Self

Create a new memory result with Arc columns and shared rows (zero-copy for both)

pub fn with_arc_all( columns: CompactArc<Vec<String>>, rows: CompactArc<Vec<Row>>, ) -> Self

Create a new memory result with both Arc columns and Arc rows (fully zero-copy) This is the most efficient constructor for cached/shared results

pub fn empty() -> Self

Create an empty memory result

pub fn with_columns(columns: Vec<String>) -> Self

Create with columns only (no rows yet)

pub fn with_schema(columns: Vec<String>, rows: RowVec, _schema: Schema) -> Self

Create with schema

pub fn add_row(&mut self, row: Row)

Add a row to the result

pub fn row_count(&self) -> usize

Get the number of rows

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

Get row by index

pub fn into_rows(self) -> Vec<Row>

Take ownership of all rows (extracts Row from RowVec)

pub fn into_arc_rows(self) -> CompactArc<Vec<Row>>

Take rows as CompactArc for zero-copy sharing with joins Returns CompactArc<Vec> - wraps owned rows or clones CompactArc for shared

pub fn reset(&mut self)

Reset the cursor to the beginning

pub fn set_rows_affected(&mut self, count: i64)

Set rows affected (for modification results)

pub fn set_last_insert_id(&mut self, id: i64)

Set last insert ID

Trait Implementations

impl QueryResult for ExecutorResult

fn columns(&self) -> &[String]

Returns the column names in the result

fn columns_arc(&self) -> Option<CompactArc<Vec<String>>>

Returns column names as Arc for zero-copy sharing

fn next(&mut self) -> bool

Moves the cursor to the next row

fn scan(&self, dest: &mut [Value]) -> Result<()>

Scans the current row into the provided values

fn row(&self) -> &Row

Returns the current row directly without copying

fn take_row(&mut self) -> Row

Returns the number of rows affected by an INSERT, UPDATE, or DELETE

fn last_insert_id(&self) -> i64

Returns the last inserted ID for an INSERT operation

fn try_into_arc_rows(&mut self) -> Option<CompactArc<Vec<Row>>>

Try to extract all rows as CompactArc<Vec> for zero-copy joins

fn with_aliases( self: Box<Self>, aliases: FxHashMap<String, String>, ) -> Box<dyn QueryResult>

Sets column aliases for this result

fn estimated_count(&self) -> Option<usize>

Returns an estimate of the total number of rows in the result.
