Struct tiberius::Row

pub struct Row { /* fields omitted */ }

A row of data from a query.

Implementations

impl Row

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

Columns defining the row data. Columns listed here are in the same order as the resulting data.

pub fn len(&self) -> usize

Returns the amount of columns in the row

pub fn get<'a, I, R>(&'a self, idx: I) -> R where
    I: QueryIdx,
    R: TryFrom<&'a ColumnData<'a>, Error = Error>, 

Retrieve a column's value for a given column index

Panics

• the requested type conversion (SQL->Rust) is not possible
• the given index is out of bounds (column does not exist)

pub fn try_get<'a, I, R>(&'a self, idx: I) -> Result<Option<R>> where
    I: QueryIdx,
    R: TryFrom<&'a ColumnData<'a>, Error = Error>, 

Retrieve a column's value for a given column index.

Returns None if:

• Index is out of bounds.
• Column is null.

Returns an error if:

• Column data conversion fails.

pub fn into_first<'a, R>(self) -> Result<Option<R>> where
    R: TryFrom<ColumnData<'a>, Error = Error>, 

Takes the first column data out from the row, consuming the row.

Returns None if:

• Row has no data.
• Column is null.

Returns an error if:

• Column data conversion fails.

Trait Implementations

impl Debug for Row

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

Formats the value using the given formatter.

impl IntoIterator for Row

type Item = ColumnData<'static>

The type of the elements being iterated over.

type IntoIter = IntoIter<Self::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
