Struct AggregateQuery 

pub struct AggregateQuery {
    pub root_entity: String,
    pub aggregations: Vec<Aggregation>,
    pub filter: Option<Filter>,
}

An aggregate query for analytics operations.

Fields

root_entity: String

Root entity type to aggregate.

aggregations: Vec<Aggregation>

Aggregation operations to perform.

filter: Option<Filter>

Optional filter to apply before aggregation.

Implementations

impl AggregateQuery

pub fn new(root_entity: impl Into<String>) -> Self

Create a new aggregate query for an entity.

pub fn with_aggregation(self, aggregation: Aggregation) -> Self

Add an aggregation operation.

pub fn count(self) -> Self

Add a COUNT(*) aggregation.

pub fn sum(self, field: impl Into<String>) -> Self

Add a SUM aggregation.

pub fn avg(self, field: impl Into<String>) -> Self

Add an AVG aggregation.

pub fn min(self, field: impl Into<String>) -> Self

Add a MIN aggregation.

pub fn max(self, field: impl Into<String>) -> Self

Add a MAX aggregation.

pub fn with_filter(self, filter: Filter) -> Self

Set a filter for this query.

Trait Implementations

impl Archive for AggregateQuery

where String: Archive, Vec<Aggregation>: Archive, Option<Filter>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedAggregateQuery

The archived representation of this type.

type Resolver = AggregateQueryResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for AggregateQuery

fn clone(&self) -> AggregateQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateQuery

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AggregateQuery

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<AggregateQuery, __D> for Archived<AggregateQuery>

where String: Archive, <String as Archive>::Archived: Deserialize<String, __D>, Vec<Aggregation>: Archive, <Vec<Aggregation> as Archive>::Archived: Deserialize<Vec<Aggregation>, __D>, Option<Filter>: Archive, <Option<Filter> as Archive>::Archived: Deserialize<Option<Filter>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<AggregateQuery, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for AggregateQuery

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

impl<__S: Fallible + ?Sized> Serialize<__S> for AggregateQuery

where String: Serialize<__S>, Vec<Aggregation>: Serialize<__S>, Option<Filter>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for AggregateQuery

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
