Struct InstanceAggregation

pub struct InstanceAggregation {
    pub target: StreamReference,
    pub caller: StreamReference,
    pub selection: InstanceSelection,
    pub aggr: InstanceOperation,
    /* private fields */
}

Represents an instance of an instance aggregation

Fields

caller: StreamReference

The stream calling and evaluating this window

selection: InstanceSelection

A filter over the instances

aggr: InstanceOperation

The operation to be performed over the instances

Trait Implementations

impl Aggregation for InstanceAggregation

fn reference(&self) -> WindowReference

Returns the reference of the window

fn id(&self) -> ExprId

Returns the Id of the expression in which this window is accessed

impl Clone for InstanceAggregation

fn clone(&self) -> InstanceAggregation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceAggregation

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

Formats the value using the given formatter.

impl PartialEq for InstanceAggregation

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