pub fn add_rows(&mut self, rows: Vec<Vec<Value>>) -> &mut Self

Adds rows

pub fn get_rows(&self) -> &Vec<Vec<Value>>

Returns a reference to the rows

pub fn get_rows_mut(&mut self) -> &mut Vec<Vec<Value>>

Returns a mut reference to the rows

pub fn n_rows(&self) -> usize

Returns the number of rows

pub fn get_types(&self) -> Option<Vec<Type>>

Gets a reference to the column types

pub fn into_parts(self) -> QueryDataParts

Extracts the parts

impl QueryData

pub fn to_bytes(self, format: Format) -> Result<Vec<u8>, Error>

Converts to bytes

pub fn from_bytes( bytes: &[u8], format: Format, mapping: Option<&[(&str, Type)]>, ) -> Result<Self, Error>

Trait Implementations

impl Clone for QueryData

fn clone(&self) -> QueryData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryData

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

Formats the value using the given formatter.

impl Default for QueryData

fn default() -> Self

Returns the “default value” for a type.

impl Display for QueryData

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

Formats the value using the given formatter.

impl PartialEq for QueryData

fn eq(&self, other: &QueryData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
