Struct AggSpec 

#[non_exhaustive]
pub struct AggSpec {
    pub kind: AggKind,
    pub column: Option<usize>,
    pub float: bool,
    pub out_type: DataType,
}

One aggregate of a MetalOp::Aggregate.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: AggKind

The function.

column: Option<usize>

The argument column (None for count(*)).

float: bool

The argument column is floating point (min/max keep DataFusion’s NaN, signed-zero and infinity semantics).

out_type: DataType

The type DataFusion’s schema gives the result.
