Struct noria::results::Row

pub struct Row { /* fields omitted */ }

A single row from a result set.

You can access fields either by numerical index or by field index. If you want to also perform type conversion, use Row::get.

Implementations

impl Row

pub fn get<T>(&self, field: &str) -> Option<T> where
    &'a DataType: Into<T>, 

Retrieve the field of the result by the given name as a T.

Returns None if the given field does not exist.

Panics if the value at the given field cannot be turned into a T.

pub fn take(&mut self, field: &str) -> Option<DataType>

Remove the value for the field of the result by the given name.

Returns None if the given field does not exist.

Trait Implementations

impl AsRef<[DataType]> for Row

fn as_ref(&self) -> &[DataType]

Performs the conversion.

impl Debug for Row

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

Formats the value using the given formatter.

impl Deref for Row

type Target = [DataType]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Eq for Row

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

type Output = DataType

The returned type after indexing.

fn index(&self, index: &str) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Index<usize> for Row

type Output = DataType

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Into<Vec<DataType>> for Row

fn into(self) -> Vec<DataType>

Performs the conversion.

impl IntoIterator for Row

type Item = DataType

The type of the elements being iterated over.

type IntoIter = IntoIter<DataType>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'_> PartialEq<&'_ Vec<DataType>> for Row

fn eq(&self, other: &&Vec<DataType>) -> bool

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialEq<[DataType]> for Row

fn eq(&self, other: &[DataType]) -> bool

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

This method tests for !=.

impl PartialEq<Row> for Row

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

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

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

This method tests for !=.

impl PartialEq<Vec<DataType>> for Row

fn eq(&self, other: &Vec<DataType>) -> bool

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
