[−][src]Struct hdbconnect::OutputParameters
Describes output parameters, as they can be returned by procedure calls.
Methods
impl OutputParameters
[src]
pub fn try_into<'de, T>(self) -> HdbResult<T> where
T: Deserialize<'de>,
[src]
T: Deserialize<'de>,
Converts the contained values in into a plain rust value or a tuple, etc.
Errors
HdbError::Deserialization
if the conversion is not implemented.
pub fn descriptor(&self, i: usize) -> HdbResult<&ParameterDescriptor>
[src]
Returns the descriptor for the i'th parameter.
Errors
HdbError::Usage
if there is no i'th parameter.
pub fn descriptors(&self) -> &Vec<ParameterDescriptor>
[src]
Returns the descriptors.
pub fn values_mut(
&mut self
) -> &mut <Vec<HdbValue<'static>> as IntoIterator>::IntoIter
[src]
&mut self
) -> &mut <Vec<HdbValue<'static>> as IntoIterator>::IntoIter
Returns an iterator of the contained values.
