Struct AggregateOperation 

#[non_exhaustive]
pub struct AggregateOperation {
    pub alias: String,
    pub source: Option<TransformOperationSource>,
    pub group_by_column_names: Option<Vec<String>>,
    pub aggregations: Vec<Aggregation>,
}

A transform operation that groups rows by specified columns and applies aggregation functions to calculate summary values.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

alias: String

Alias for this operation.

source: Option<TransformOperationSource>

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

group_by_column_names: 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.

aggregations: Vec<Aggregation>

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

Implementations

impl AggregateOperation

pub fn alias(&self) -> &str

Alias for this operation.

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

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

pub fn group_by_column_names(&self) -> &[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.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .group_by_column_names.is_none().

pub fn aggregations(&self) -> &[Aggregation]

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

impl AggregateOperation

pub fn builder() -> AggregateOperationBuilder

Creates a new builder-style object to manufacture AggregateOperation.

Trait Implementations

impl Clone for AggregateOperation

fn clone(&self) -> AggregateOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateOperation

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

Formats the value using the given formatter.

impl PartialEq for AggregateOperation

fn eq(&self, other: &AggregateOperation) -> 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.
