Enum AggregatedValue 

pub enum AggregatedValue {
    Count(u64),
    Sum(Value),
    Avg(Value),
    Min(Value),
    Max(Value),
}

Result of a single aggregate function applied to a group.

Each variant corresponds to a variant of AggregateFunction. Count is always a u64; the remaining variants wrap a Value whose concrete kind matches the aggregated column’s data type.

Variants

Count(u64)

Number of rows counted by AggregateFunction::Count.

Sum(Value)

Sum produced by AggregateFunction::Sum.

Avg(Value)

Average produced by AggregateFunction::Avg.

Min(Value)

Minimum produced by AggregateFunction::Min.

Max(Value)

Maximum produced by AggregateFunction::Max.

Trait Implementations

impl CandidType for AggregatedValue

fn _ty() -> Type

fn _ty_doc() -> TypeDoc

fn id() -> TypeId

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

where __S: Serializer,

fn ty() -> Type

impl Clone for AggregatedValue

fn clone(&self) -> AggregatedValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregatedValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AggregatedValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AggregatedValue

fn eq(&self, other: &AggregatedValue) -> 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 AggregatedValue

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.
