Struct Row 

pub struct Row { /* private fields */ }

Implementations

impl Row

pub fn new(columns: Columns, values: Vec<Value>) -> Self

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

Read a column by name, converted to T.

The error names the column, because “invalid type” with no column name is the least useful message a database layer can produce.

pub fn get_at<T: FromValue>(&self, index: usize) -> Result<T>

Read a column by position.

pub fn get_or<T: FromValue>(&self, column: &str, default: T) -> T

Read a column, falling back when it is absent or NULL.

pub fn value(&self, column: &str) -> Result<&Value>

pub fn value_at(&self, index: usize) -> Result<&Value>

The value at a position, for a result whose columns the database did not name.

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

pub fn to_json(&self) -> Json

The row as a JSON object — what an API handler usually wants next.

Trait Implementations
