Struct AggregateOrder 

pub struct AggregateOrder { /* private fields */ }

Groups by the aggregate of a column: the column needs an aggregate in the view. Ties, and groups without the aggregate, keep the key order.

Implementations

impl AggregateOrder

pub fn new(column: impl GridColumns, direction: SortDirection) -> Self

Orders groups by their aggregate of column.

pub fn column(&self) -> ColumnIx

The column whose aggregate orders the groups.

pub fn direction(&self) -> SortDirection

The direction.

Trait Implementations

impl Clone for AggregateOrder

fn clone(&self) -> AggregateOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateOrder

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

Formats the value using the given formatter.

impl<R: GridRow> GroupOrder<R> for AggregateOrder

fn compare( &self, a: &GroupOrderContext<'_>, b: &GroupOrderContext<'_>, ) -> Ordering

Compares two sibling groups.

fn depends_on(&self) -> ColumnSet

The columns whose changes can reorder groups: the order’s aggregates. Empty for an order that reads keys alone.
