Struct AggregateOperationBuilder 

#[non_exhaustive]
pub struct AggregateOperationBuilder { /* private fields */ }

A builder for AggregateOperation.

Implementations

impl AggregateOperationBuilder

pub fn alias(self, input: impl Into<String>) -> Self

Alias for this operation.

This field is required.

pub fn set_alias(self, input: Option<String>) -> Self

Alias for this operation.

pub fn get_alias(&self) -> &Option<String>

Alias for this operation.

pub fn source(self, input: TransformOperationSource) -> Self

The source transform operation that provides input data for the aggregation.

This field is required.

pub fn set_source(self, input: Option<TransformOperationSource>) -> Self

The source transform operation that provides input data for the aggregation.

pub fn get_source(&self) -> &Option<TransformOperationSource>

The source transform operation that provides input data for the aggregation.

pub fn group_by_column_names(self, input: impl Into<String>) -> Self

Appends an item to group_by_column_names.

To override the contents of this collection use set_group_by_column_names.

The list of column names to group by when performing the aggregation. Rows with the same values in these columns will be grouped together.

pub fn set_group_by_column_names(self, input: Option<Vec<String>>) -> Self

The list of column names to group by when performing the aggregation. Rows with the same values in these columns will be grouped together.

pub fn get_group_by_column_names(&self) -> &Option<Vec<String>>

The list of column names to group by when performing the aggregation. Rows with the same values in these columns will be grouped together.

pub fn aggregations(self, input: Aggregation) -> Self

Appends an item to aggregations.

To override the contents of this collection use set_aggregations.

The list of aggregation functions to apply to the grouped data, such as SUM, COUNT, or AVERAGE.

pub fn set_aggregations(self, input: Option<Vec<Aggregation>>) -> Self

The list of aggregation functions to apply to the grouped data, such as SUM, COUNT, or AVERAGE.

pub fn get_aggregations(&self) -> &Option<Vec<Aggregation>>

The list of aggregation functions to apply to the grouped data, such as SUM, COUNT, or AVERAGE.

pub fn build(self) -> Result<AggregateOperation, BuildError>

Consumes the builder and constructs a AggregateOperation. This method will fail if any of the following fields are not set:

• alias
• aggregations

Trait Implementations

impl Clone for AggregateOperationBuilder

fn clone(&self) -> AggregateOperationBuilder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AggregateOperationBuilder

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

Formats the value using the given formatter.

impl Default for AggregateOperationBuilder

fn default() -> AggregateOperationBuilder

Returns the “default value” for a type.

impl PartialEq for AggregateOperationBuilder

fn eq(&self, other: &AggregateOperationBuilder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
