Struct hdbconnect::Row

pub struct Row { /* fields omitted */ }

A generic implementation of a single line of a ResultSet.

Methods

impl Row

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

Factory for row.

fn len(&self) -> usize

Returns the length of the row.

fn is_empty(&self) -> bool

Returns true if the row contains no value.

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

Removes and returns the last value.

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

Returns the name of the i'th column

fn reverse_values(&mut self)

Reverses the order of the values

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

Returns a clone of the ith value.

fn pop_into<'de, T>(&mut self) -> Result<T, <Row as DeserializableRow>::E> where
    T: Deserialize<'de>, 

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

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.

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.

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

Swaps out a field and converts it into a CLOB.

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

Swaps out a field and converts it into a BLOB.

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

Converts the Row into a rust value.

Trait Implementations

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, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl IntoIterator for Row

type Item = TypedValue

The type of the elements being iterated over.

type IntoIter = IntoIter<TypedValue>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Display for Row

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

Formats the value using the given formatter.
