Struct mysql_async::Row

pub struct Row { /* fields omitted */ }

Row of a result set.

Row could be indexed by numeric column index or by column name.

Methods

impl Row

fn len(&self) -> usize

Returns length of a row.

fn as_ref(&self, index: usize) -> Option<&Value>

Returns reference to the value of a column with index index if it exists and wasn't taken by Row::take method.

Non panicking version of row[usize].

fn get<T, I>(&mut self, index: I) -> Option<T> where
    T: FromValue,
    I: ColumnIndex, 

Will copy value at index index if it was not taken by Row::take earlier, then will convert it to T.

fn take<T, I>(&mut self, index: I) -> Option<T> where
    T: FromValue,
    I: ColumnIndex, 

Will take value of a column with index index if it exists and wasn't taken earlier then will converts it to T.

fn unwrap(self) -> Vec<Value>

Unwraps values of a row.

Panics

Panics if any of columns was taken by take method.

Trait Implementations

impl FromRow for Row

fn from_row(row: Row) -> Row

fn from_row_opt(row: Row) -> Result<Row>

impl Clone for Row

fn clone(&self) -> Row

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Row

fn eq(&self, __arg_0: &Row) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Row) -> bool

This method tests for !=.

impl Debug for Row

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Index<usize> for Row

type Output = Value

The returned type after indexing

fn index<'a>(&'a self, index: usize) -> &'a Value

The method for the indexing (container[index]) operation

impl<'a> Index<&'a str> for Row

type Output = Value

The returned type after indexing

fn index<'r>(&'r self, index: &'a str) -> &'r Value

The method for the indexing (container[index]) operation
