Struct OwnedRow 

pub struct OwnedRow { /* private fields */ }

A row copied out of a driver, addressable by column name.

Implementations

impl OwnedRow

pub fn new() -> Self

An empty row.

pub fn with(self, name: impl Into<String>, value: impl Into<Cell>) -> Self

Set a column.

pub fn set(&mut self, name: impl Into<String>, value: impl Into<Cell>)

Set a column in place.

pub fn snapshot(row: &dyn Row, columns: &[ColumnRequest]) -> Result<Self>

Copy the requested columns out of a driver row.

Each column is read through the getter its ColumnType names, which is the same dispatch Rainier ORM’s own decoder performs — so a value that round-trips through here decodes identically to one read directly.

pub fn is_empty(&self) -> bool

Whether the row holds no columns.

pub fn len(&self) -> usize

How many columns the row holds.

pub fn cell(&self, name: &str) -> Option<&Cell>

The raw cell at name, if it was read.
