Struct SpgRow 

pub struct SpgRow { /* private fields */ }

A single result row from an SPG-shape SELECT.

Implementations

impl SpgRow

pub fn new( columns: Arc<Vec<SpgColumn>>, by_name: Arc<HashMap<String, usize>>, values: Vec<EngineValue>, ) -> Self

Construct a row given the shared column metadata + the cell values for this specific row. Adapter-internal.

Trait Implementations

impl Clone for SpgRow

fn clone(&self) -> SpgRow

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ColumnIndex<SpgRow> for &str

fn index(&self, row: &SpgRow) -> Result<usize, Error>

Returns a valid positional index into the row or statement, ColumnIndexOutOfBounds, or, ColumnNotFound.

impl ColumnIndex<SpgRow> for usize

fn index(&self, row: &SpgRow) -> Result<usize, Error>

Returns a valid positional index into the row or statement, ColumnIndexOutOfBounds, or, ColumnNotFound.

impl Debug for SpgRow

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Row for SpgRow

type Database = Spg

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

Gets all columns in this statement.

fn try_get_raw<I>(&self, index: I) -> Result<SpgValueRef<'_>, Error>

where I: ColumnIndex<Self>,
