Struct hdbconnect::OutputParameters

pub struct OutputParameters { /* fields omitted */ }

Describes output parameters, as they can be returned by procedure calls.

Methods

impl OutputParameters

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

Converts the contained values in into a plain rust value or a tuple, etc.

pub fn descriptor(&self, i: usize) -> HdbResult<&ParameterDescriptor>

Returns the descriptor for the i'th parameter.

pub fn descriptors(&self) -> &Vec<ParameterDescriptor>

Returns the descriptors.

pub fn values_mut(
    &mut self
) -> &mut <Vec<HdbValue<'static>> as IntoIterator>::IntoIter

Returns an iterator of the contained values.

Trait Implementations

impl Display for OutputParameters

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

Formats the value using the given formatter.

impl Debug for OutputParameters

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

Formats the value using the given formatter.

impl DeserializableRow for OutputParameters

type V = HdbValue<'static>

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 current length of the row (which is decremented with each call to next()).

fn next(&mut self) -> Option<HdbValue<'static>>

Removes and returns the next value.

fn number_of_fields(&self) -> usize

Returns the number of fields in a complete row.

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

Returns the name of the column at the specified index.

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.
