Implementations§

Source§

impl ExecutorResult

Source

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

Create a new memory result with columns and pooled rows

Source

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

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

Source

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<Row> when reading from semantic cache

Source

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)

Source

pub fn empty() -> Self

Create an empty memory result

Source

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

Create with columns only (no rows yet)

Source

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

Add a row to the result

Source

pub fn row_count(&self) -> usize

Get the number of rows

Source

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

Get row by index

Source

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

Take ownership of all rows (extracts Row from RowVec)

Source

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

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

Source

pub fn reset(&mut self)

Reset the cursor to the beginning

Source

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

Set rows affected (for modification results)

Source

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

Set last insert ID
