Struct BoundAggregate 

pub struct BoundAggregate {
    pub func: AggregateFunc,
    pub external: Option<Vec<u8>>,
    pub distinct: bool,
    pub arguments: Vec<BoundExpr>,
    pub star: bool,
    pub collation: Collation,
    pub filter: Option<BoundExpr>,
    pub order_by: Vec<BoundOrderTerm>,
}

One aggregate the statement computes.

Fields

func: AggregateFunc

Which aggregate.

external: Option<Vec<u8>>

The name, when the aggregate is one an application registered.

distinct: bool

Whether DISTINCT was written.

arguments: Vec<BoundExpr>

The arguments, or empty for count(*).

star: bool

Whether the call was count(*).

collation: Collation

The collation the aggregate compares with.

filter: Option<BoundExpr>

The FILTER (WHERE ...) clause, when one was written.

A row the filter does not keep is not folded in at all - it does not count, it does not sum and it does not appear in a group_concat.

order_by: Vec<BoundOrderTerm>

The ORDER BY written inside the argument list.

Empty for nearly every call. It matters to the aggregates whose answer depends on the order the rows arrive in - group_concat and the JSON group aggregates - and SQLite accepts it on any of them.
