Struct Row 

pub struct Row { /* private fields */ }

A row returned from a query. Contains column descriptions and raw data.

Column descriptors are shared via Rc across all rows in a result set, avoiding expensive deep clones on every DataRow message.

Column values use [CompactBytes] — values ≤ 24 bytes are stored inline (no heap allocation), which covers all binary-format scalar types.

Implementations

impl Row

pub fn new(columns: Rc<Vec<ColumnDesc>>, raw_values: Vec<Option<&[u8]>>) -> Row

Create a new row from shared column descriptions and raw column data.

Small values (≤ 24 bytes) are stored inline with zero heap allocation.

pub fn mock(names: &[&str], values: &[PgValue]) -> Row

Safely create a mock row for testing, bypassing wire protocols.

pub fn len(&self) -> usize

Get the number of columns.

pub fn is_empty(&self) -> bool

Check if the row is empty.

pub fn get(&self, index: usize) -> Result<PgValue, PgError>

Get a column value by index as a PgValue.

pub fn get_by_name(&self, name: &str) -> Result<PgValue, PgError>

Get a column value by name as a PgValue.

pub fn get_typed<T>(&self, index: usize) -> Result<T, PgError>

where T: FromSql,

Get a typed value by column index using the FromSql trait.

Example

let name: String = row.get_typed(0)?;
let age: Option<i32> = row.get_typed(1)?;

pub fn get_typed_by_name<T>(&self, name: &str) -> Result<T, PgError>

where T: FromSql,

Get a typed value by column name using the FromSql trait.

pub fn get_str(&self, index: usize) -> Result<Option<&str>, PgError>

Get a column as a string (text representation).

pub fn get_i32(&self, index: usize) -> Result<Option<i32>, PgError>

Get a column as i32.

pub fn get_i64(&self, index: usize) -> Result<Option<i64>, PgError>

Get a column as i64.

pub fn get_bool(&self, index: usize) -> Result<Option<bool>, PgError>

Get a column as bool.

pub fn get_f64(&self, index: usize) -> Result<Option<f64>, PgError>

Get a column as f64.

pub fn get_uuid(&self, index: usize) -> Result<Option<[u8; 16]>, PgError>

Get a column as a UUID string (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

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

Get column descriptions.

pub fn column_name(&self, index: usize) -> Option<&str>

Get a column name by index.

pub fn column_index(&self, name: &str) -> Option<usize>

Find a column index by name.

Trait Implementations

impl Debug for Row

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

Formats the value using the given formatter.
