Enum AggregateValue 

pub enum AggregateValue {
    Integer(i64),
    Float(f64),
    Text(String),
    Null,
}

A value produced by an aggregate expression.

Variants

Integer(i64)

Integer aggregate result (e.g., COUNT)

Float(f64)

Floating-point aggregate result (SUM/AVG of decimals)

Text(String)

String aggregate result (SAMPLE, GROUP_CONCAT)

Null

No value — group was empty or variable was unbound throughout
