Struct PivotConfig 

pub struct PivotConfig {
    pub row_fields: Vec<usize>,
    pub column_fields: Vec<usize>,
    pub value_field: Option<usize>,
    pub aggregation: AggregationFn,
    pub filter_fields: Vec<usize>,
    pub show_row_subtotals: bool,
    pub show_column_subtotals: bool,
    pub show_row_grand_total: bool,
    pub show_column_grand_total: bool,
    pub blank_label: String,
    pub value_format: Option<NumberFormat>,
}

Field assignments plus display options for a pivot view.

All field references are source column indices into the grid’s GridData::columns.

Fields

row_fields: Vec<usize>

Columns whose distinct values form the row axis, outermost first.

column_fields: Vec<usize>

Columns whose distinct values form the column axis, outermost first.

value_field: Option<usize>

The measure column. None renders an empty pivot prompting for configuration.

aggregation: AggregationFn

How intersection values are combined.

filter_fields: Vec<usize>

Columns available as source-row filters (the Filters zone). The actual predicate state lives on the pivot state, not the config.

show_row_subtotals: bool

Show subtotal values on expanded row group headers.

show_column_subtotals: bool

Append a “Total” column after each expanded column group.

show_row_grand_total: bool

Show the grand-total row at the bottom.

show_column_grand_total: bool

Show the grand-total column at the right.

blank_label: String

Label used when a grouping value is CellValue::None.

value_format: Option<NumberFormat>

Optional number-format override for value cells. None falls back to the value column’s resolved format.

Implementations

impl PivotConfig

pub fn is_ready(&self) -> bool

true when there is enough configuration to compute a pivot: a value field plus at least one axis field.

pub fn zone_of(&self, field: usize) -> Option<PivotZone>

The zone field is currently assigned to, if any.

pub fn fields_in(&self, zone: PivotZone) -> Vec<usize>

Fields currently assigned to zone, in display order.

pub fn move_field( &mut self, field: usize, zone: PivotZone, index: Option<usize>, )

Assign field to zone at index (clamped; None appends).

A field lives in at most one zone, so any previous assignment is removed first. Dropping onto PivotZone::Values replaces the current value field — the zone holds exactly one.

pub fn remove_field(&mut self, field: usize)

Remove field from whatever zone holds it. No-op when unassigned.

pub fn clamp_to_columns(&mut self, column_count: usize)

Drop every assignment that refers to a column index outside 0..column_count. Call after the source schema changes.

Trait Implementations

impl Clone for PivotConfig

fn clone(&self) -> PivotConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PivotConfig

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

Formats the value using the given formatter.

impl Default for PivotConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PivotConfig

fn eq(&self, other: &PivotConfig) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
