Struct Row 

pub struct Row { /* private fields */ }

A result row.

Values are kept in their storage class and decoded on access with FromValue, so the same column can be read as i64, bool or String. The column index is shared between all rows of one result set.

Implementations

impl Row

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

The column names in SELECT order.

pub fn len(&self) -> usize

The number of columns.

pub fn is_empty(&self) -> bool

Whether the row has no columns.

pub fn has(&self, column: &str) -> bool

Whether a column exists.

pub fn get<T: FromValue>(&self, column: impl ColumnIndex) -> Result<T>

Decodes a column.

Errors

Returns Error::Decode when the column does not exist or the value cannot be converted to T.

pub fn try_get<T: FromValue>( &self, column: impl ColumnIndex, ) -> Result<Option<T>>

Decodes a column, returning None when it does not exist.

Errors

Returns Error::Decode when the value cannot be converted to T.

pub fn raw(&self, column: impl ColumnIndex) -> Option<&Value>

The raw storage value of a column, or None when absent.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Value)>

Iterates over (name, value) pairs in column order.

Trait Implementations

impl Clone for Row

fn clone(&self) -> Self

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.
