Enum AggregateFunc 

#[non_exhaustive]
pub enum AggregateFunc {
    Count,
    CountDistinct,
    Sum,
    Avg,
    Min,
    Max,
}

Aggregation functions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Count

Count rows: COUNT(*)

CountDistinct

Count distinct values: COUNT(DISTINCT field)

Sum

Sum values: SUM(field)

Avg

Average value: AVG(field)

Min

Minimum value: MIN(field)

Max

Maximum value: MAX(field)

Trait Implementations

impl Clone for AggregateFunc

fn clone(&self) -> AggregateFunc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateFunc

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

Formats the value using the given formatter.

impl PartialEq for AggregateFunc

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