Struct AggregateQuery 

pub struct AggregateQuery {
    pub table: String,
    pub filter: Option<Expr>,
    pub group_by: Vec<String>,
    pub aggregates: Vec<Aggregate>,
    pub having: Option<Expr>,
}

A grouped/aggregated query. Rows are scanned, optionally filtered, grouped by group_by key columns, reduced with aggregates, and finally filtered by having. With no group_by, the whole (filtered) table is one group.

Fields

table: String

filter: Option<Expr>

group_by: Vec<String>

aggregates: Vec<Aggregate>

having: Option<Expr>

Predicate applied to each produced group row. Column references resolve to the group key columns or aggregate aliases.

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<AggregateQuery, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde 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 Serialize for AggregateQuery

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
