Struct Row 

pub struct Row { /* private fields */ }

A single row from a query result.

Holds the raw Vec<Value> (one slot per column) and a shared index mapping column names to slot positions. Lookup by name is O(1) via the shared Arc<HashMap>, so iteration allocates no per-row map.

Implementations

impl Row

pub fn get(&self, name: &str) -> Option<&Value>

Look up a value by column name.

pub fn at(&self, idx: usize) -> Option<&Value>

Look up a value by column position.

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

All column names, in schema order.

pub fn values(&self) -> &[Value]

All values, in schema order.

pub fn len(&self) -> usize

Number of columns in this row.

pub fn is_empty(&self) -> bool

pub fn into_map(self) -> HashMap<String, Value>

Convert to a HashMap<String, Value> for callers that prefer map-shaped rows. Allocates one HashMap and clones every column name.

Trait Implementations

impl Clone for Row

fn clone(&self) -> Row

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Row

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

Formats the value using the given formatter.

impl Index<&str> for Row

type Output = Value

The returned type after indexing.

fn index(&self, name: &str) -> &Value

Performs the indexing (container[index]) operation.

impl Index<usize> for Row

type Output = Value

The returned type after indexing.

fn index(&self, idx: usize) -> &Value

Performs the indexing (container[index]) operation.
