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>
