Struct hdbconnect::Row

pub struct Row { /* fields omitted */ }

A generic implementation of a single line of a ResultSet.

Methods

impl Row

pub fn new(metadata: Arc<ResultSetMetadata>, values: Vec<HdbValue>) -> Row

Factory for row.

pub fn len(&self) -> usize

Returns the length of the row.

pub fn is_empty(&self) -> bool

Returns true if the row contains no value.

pub fn pop(&mut self) -> Option<HdbValue>

Removes and returns the last value.

pub fn get_fieldname(&self, i: usize) -> HdbResult<&String>

Returns the name of the i'th column

pub fn reverse_values(&mut self)

Reverses the order of the values

pub fn cloned_value(&self, i: usize) -> HdbResult<HdbValue>

Returns a clone of the ith value.

pub fn pop_into<'de, T>(&mut self) -> HdbResult<T> where     T: Deserialize<'de>,

Pops and converts the last field into a plain rust value.

pub fn field_into<'de, T>(&mut self, i: usize) -> HdbResult<T> where     T: Deserialize<'de>,

Swaps out a field and converts it into a plain rust value.

pub fn field_into_option<'de, T>(&mut self, i: usize) -> HdbResult<Option<T>> where     T: Deserialize<'de>,

Swaps out a field and converts it into an Option of a plain rust value.

pub fn field_into_nclob(&mut self, i: usize) -> HdbResult<NCLob>

Swaps out a field and converts it into a CLOB.

pub fn field_into_clob(&mut self, i: usize) -> HdbResult<CLob>

Swaps out a field and converts it into a CLOB.

pub fn field_into_blob(&mut self, i: usize) -> HdbResult<BLob>

Swaps out a field and converts it into a BLob.

pub fn try_into<'de, T>(self) -> HdbResult<T> where     T: Deserialize<'de>,

Converts the Row into a rust value.

Trait Implementations

impl IntoIterator for Row

type Item = HdbValue

The type of the elements being iterated over.

type IntoIter = IntoIter<HdbValue>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

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 Debug for Row

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

Formats the value using the given formatter.

impl Display for Row

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

Formats the value using the given formatter.

impl DeserializableRow for Row

type V = HdbValue

The value type used by the database driver.

type E = HdbError

The error type used by the database driver.

fn len(&self) -> usize

Returns the length of the row.

fn pop(&mut self) -> Option<HdbValue>

Removes and returns the last value.

fn get_fieldname(&self, field_idx: usize) -> Option<&String>

Returns the name of the column at the specified index

fn reverse_values(&mut self)

Reverses the order of the values. This method will be before deserialization of the row into a tuple starts, which uses pop() to access individual values.

fn into_typed<'de, T>(self) -> Result<T, Self::E> where     T: Deserialize<'de>,

Converts the row into a struct, a tuple, or (if applicable) into a plain rust value.
